NewLight Point

NewLight_Point in End Game chapter (used for the portal).

newLight_Point is a point entity available in Black Mesa. It creates an invisible deferred light source that shines in all directions, includes godrays and lightcookies.

Warning:New lights use expensive gbuffer, that means that with this entity your scene rendering at least 5 times, which makes your level very expensive, considering that XenEngine uses 32-bit architecture and DirectX 9.5 rendering. In large quantities, new lights can greatly heat up your computer and also cause large FPS drops (depending on difficulty of your map and how your area open). Use wisely.

Note:You can have only 512 point light entities placed in the map editor.

Represented by class CNewLightPoint.

Todo: Rework this page.

Pitch Yaw Roll (Y Z X) (angles) <angle> !FGD

This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.

Note:There is almost no differences if you're using point light with no texture. Things changes if you're using textures.

bUseOldFallOff (bUseOldFallOff) <choices> !FGD 

Deprecated.
Enable old falloff similar to light/light_spot.

• 0: No
• 1: Yes

Light Color (LightColor) <color255>

The RGB color of the light. Colors must be between 0 and 255.

Light Intensity (Intensity) <float>

Intensity/brightness of the light. It's RGB * intensity.

Note:With 0 it will make the light disabled, including the effects. Doesn't affect shadows.

Range (Range) <float>

Range of the light, or how far the light source can illuminate. Measured in Hammer Units.

Warning:This is one of the parameters that affects performance in the game. Smaller values ​​allow you to process less geometry and save performance.

Important:Range is limited, the limit depends on intensity value. Do not use values ​​bigger than the intensity value allows.

Examples

Range - 50 Range - 1000 Range - 15000

Light Type (LightType) <choices>

Type of the light. This affects the behavior of the light source with parent, enable/disable dynamic models in shadowmaps, enable/disable static shadowmaps.

• 0: Static - used only static shadowmaps, this means that shadows are cast only by static objects (prop_static, geometry, etc). Cannot move with parent.

Important:Brush entities and bmodels are also included in static shadowmaps and they never update (including func_physbox).

Note:Static shadowmaps will update after save reload (only once).

• 1: Stationary - the same as Static, but with dynamic shadows for dynamic models.
• 2: Dynamic - lighting don't use static shadowmaps at all. It uses dynamic shadows for static objects and dynamic models. This type also can move with parent. This type is expensive, usually used for moving lights, but also can be used if you're getting issues due to static shadowmaps.

Examples

Note:Note that shadow from metal box and grate box are flying on first and second pictures, that's because both was placed in air on map spawn. Doesn't happen on third picture, because the light updated shadow for both. Static Stationary Dynamic

HasShadow (HasShadow) <choices>

Sets shadows state for the light, enabled or disabled. Remember that the default choices is No.

• 0: No
• 1: Yes

Examples

Has Shadow - NO Has Shadow - YES

Examples

256 512 1024

Important:You cannot use any value from here an unlimited number of times. More information below.

ShadowRadius (ShadowRadius) <float>

Radius of shadow edges for soft shadows. If its value is negative, code will auto assign a value depending on ShadowLod. These code based values can be adjusted via convars nr_shadow_rad_High, nr_shadow_rad_Med and nr_shadow_rad_Low.

Examples

ShadowRadius - 0.0001 ShadowRadius - 1 ShadowRadius - 5

Tip:Don't use very low values, because the shadows will look like stairs. Also don't use very high values, because the noise will spoil them a lot, or you'll see only noise.

NearZ (NearZ) <float>

NearZ used by shadowmap camera for this light. This is the distance at which the light source will start cast shadows.

Slope Depth Bias used for surfaces having aliasing due to steep angles with light.

Examples

SlopeDepthBias - 0.2 SlopeDepthBias - 8 SlopeDepthBias - 20

NormalBias (NormalBias) <float>

While rendering objects into shadowmaps, each vertex will be moved along -ve Normal direction, giving it an appearance of shrinking while rendering to shadowmaps. This property determines the amount of Units to be moved. Helps with shadow aliasing.

Examples

Note:You will not see any changes if your material doesn't not provide bumpmap. NormalBias - 1 NormalBias - 5 NormalBias - 20

Important:Increasing this value will make shadows between different surfaces less accurate, greate example is third picture in examples, there you can see "two" shadows from railing.

Bug:Numbers lower than 0.8 can cause huge graphics issues. Example.

Tip:Increase this value if you are getting aliasing issues like this.

Shadow map slots

Shadow map slots is how many lights with shadows you can have per level. There are 3 separate shadow map slots, High (for lights with 1024 value for ShadowMap LOD property), Medium (for lights with 512 value for ShadowMap LOD property) and Low (for lights with 256 value for ShadowMap LOD property).

In High and Medium you can have 48 separate shadow maps, for Low you can have 47 separate shadow maps (143 shadow maps in total).

Each spot light with shadows takes 1 shadow map slot, so you can have 48/47 spot lights with shadows, if they are using the same value for ShadowMap LOD property.

Each point light with shadows takes 6 shadow map slots. This is due to point light isn't just omnidirectional light source, it's 6 spot lights in one entity. This means that you can have 8 point lights with shadows, if they are using the same value for ShadowMap LOD property. You can increase this value if you need, just disable shadows for one of the shadow face properties.

If one of the shadow map slots is full - you will not be able to have shadows for more lights with such shadow quality, you will need to use other value for ShadowMap LOD property.

Point lights and spot lights doesn't counts separately. You can't have 48 spot lights with 8 point lights, but you can have 6 spot lights with 7 point lights.

You can free up shadow map slots with Kill input. So, you can place triggers which will Kill lights that player can't see and spawn new lights via point_template (uncheck the second flag for point_template, this prevents some bugs). This helps a lot when you want to have many dynamic lights in different areas.

Important to note that due to some engine bugs you can't use many lights with shadows. Some tests show that 9th point light cause lights with shadows to be very glitchy. This can be done with spot lights as well. So don't be surprised if at some point you find something like this.

• 

  The bug example.

It looks like you can workaround it if you will switch ShadowMap LOD property values from higher to lower.

Tip:You can use nr_debug_print_shadow_slots_info to get full info about shadowmap slots.

Lighting behavior with VIS and areaportals

Static type

Static type is the most stable, since its shadows are baked in and updates only with save loads or while lighting turning on. It shows all shadows even with closed areaportal.

• 

  Areaportal is open.

• 

  Areaportal is closed.

Stationary type

Shadows for static props and brushes are baked, but not for physics props and other dynamic models. This means that shadows from dynamic models will disappear if they are hidden by a closed areaportal or if VIS is hiding such objects. Shadows for static props and brushes will not disappear.

• 

  Areaportal is open.

• 

  Areaportal is closed.

In some cases, this can be noticeable if dynamic model creates a large shadow.

• 

  Areaportal hides the box, note that there is no shadow.

• 

  Areaportal shows the box, now there is a shadow of the box.

With mat_wireframe 1.

• 

  Areaportal hides the box.

• 

  Areaportal shows the box.

Dynamic type

Shadows for static props and world geometry are baked, but not for dynamic models and brushes. This means that shadows from dynamic models and brushes will disappear if they are hidden by a closed areaportal or if VIS is hiding such objects. Shadows for static props and world geometry will not disappear. Moving lighting will update shadows for static props and world geometry, even with closed areaportal.

• 

  Areaportal is open.

• 

  Areaportal is closed.

Player spawn and areaportals

If player spawned in position where areaportal don't hide objects - shadows will be fine. Otherwise, static shadowmap will not see models with bmodels and will bake shadows only for world geometry and displacements. This problem is not relevant only for Dynamic light type. The problem disappears after save reload from proper position.

• 

  Player spawned in position where areaportal don't hide objects. The columns are func_detail, the pipes are prop_static.

• 

  Player spawned in position where areaportal hide objects. Note that the columns and pipes don't have any shadows.

Lighting behavior with start/end fade dist for prop_static

This mechanic has some issues with static shadowmaps. It seems that there are limitations that don't allow to fix these issues, or this issues was not noticed at the development stage.

Static type

If player spawns in fade radius - shadows will never disappear (until save reload if out of radius).

• 

  In radius.

• 

  Out of radius.

If player spawns out of radius. - shadows will never appear (until save reload in radius).

• 

The same for props with both Start and End fade dist.

Stationary type

The above mentioned issues are also available for this type.

Appears issue for prop_static with both Start and End fade dist.

If player spawns in Start fade radius - shadows will never disappear (until save reload if out of radius). The same happens if player spawns in End fade radius.

If player spawns out of radius - shadows will appear if you are in End fade radius and disappear if you are in Start fade radius (until save reload in radius). This happens because prop_static actually disappears completely, and creates a separate object as a fading model (this is also why decals disappear if player is out of Start fade radius).

• 

  In radius.

• 

  Out of Start fade radius.

• 

  Out of End fade radius.

Dynamic type

Dynamic type don't use static shadowmaps at all. This means that there is no problems with fading prop_static at all.

Important:All the issues is also available for func_lod.

nr_shadow_max_passes_per_frame	16	Float	Frame per second in shadowmaps. The higher the value, the smoother and faster the shadows from objects can change. The recommended value is 24-28, not higher. Important:The game can change its value independently, depending on the number of shadowmaps in frame. The game returns to the previous value if the number of shadowmaps decreases. Bug:"End Game" chapter crashes with 29 and higher values.
nr_shadow_quality	4	Integer	Sets shadow quality and enable/disable shadows for all or certain objects. Controlled by Dynamic Shadow Quality option. Only 5 values are available here. 0 (Disabled) - Shadows are completely disabled. 1 (POTATO) - Shadows are available for world geometry and displacements, only for Static and Stationary light types. The shadows are very pixelated. The player's flashlight also gets very simple shadows with "stairs". 2 (Low) - Added brush entities and static props in shadowmaps, only for Static and Stationary light types. 3 (Medium) - All the shadows are also available for Dynamic light type. 4 (Hight) - Added dynamic models in shadowmaps for Stationary and Dynamic. Note:This cvar needs save reload to see changes.
mat_unlock_gfx_highend_unsupported	0	Bool	When enabled this convar will unlock extreme graphics options. There will be a significant FPS drop when running game on ULTRA or INSANE configs. Game will consume upto 3 gigs of VRAM when some of the extreme graphics options have been enabled. These high end graphics config options are not officially supported. Don't enable this unless you have at least 3.5 GHZ quad core CPU with GTX 1080. These options are mainly for debugging and modders.
nr_lights_quality	4	Integer	Sets lights quality, state (for specific entities), enable/disable effects. Controlled by Dynamic Light Quality option. Only 7 values are available here. 0 (POTATO) - Disabled muzzle flash light (regardless of muzzleflash_light), lighting from batteries (regardless of cl_battery_dlights), light sources from dynlightscript.txt, dynamic lights are also disabled for some other entities.

np_gr_quality	2	Integer	Enable/disable godrays. Controlled by God Rays option or Enable God Rays button (if used VGUI). 0 - Disabled. 1/2 - Enabled. 1 supposed to enable godrays only for newlight_dir and 2 for point lights and newlight_dir, but currently both values enable both types.
np_gr_quality_sample_count	3	Integer	Amount of samples for godrays. This affects the quality/detail of the rays. Controlled by God Rays option, although the original game never changes the value (always 3). Min value is 0, max is 4. The max value is not recommended, it has a huge impact on frame rate, at the same time it does not create a big difference in the game.
np_gr_quality_pass_count	1	Integer	Pass count. Not very clear what exactly this affects, but it significantly reduces performance, and Fancy Rays also become pretty buggy. Controlled by God Rays option, although the original game never changes the value (always 1). Min value is 0, max is 4. Use the default value only.

It prints light type (point or spot) with their index, shadowmap enabled state (for each face), shadowmaps number, new light's targetname and position of it. Below it also prints information about free shadowmap slots for each shadow resolution.
nr_debug_force_shadowmap_res	-1	Bool	Only for debugging. Forces all new lights to use specified shadowmap resolution. -1 means use value from the property.
nr_debug_force_dynamic_on_all_stationary_lights	0	Bool	Only for debugging. Forces all stationary new lights to be fully dynamic and update even baked shadows.
nr_debug_force_lightstyle	0	Integer	Only for debugging. Forces all new lights to use specified appearance/light style. Possible values are 0-13. 13 for custom style from nr_debug_force_lightstyle_custom_string. 0 means use use value from the property.
nr_debug_force_lightstyle_custom_string	1	String	Only for debugging. Forces all new lights to use custom appearance/light style. Works the same as with lightmapped lights.
nr_debug_shadow_render_internal_disable	0	Bool	Only for debugging. Forces all new lights to disable shadowmaps rendering.
nr_debug_shadow_print_indices_assignment	0	Bool	Only for debugging. Prints text to the console about all new light sources and shadowmaps after level/save loading.
nr_debug_lights_mesh	0	Bool	Only for debugging. Enable/disable new lights mesh.
nr_debug_lights_mesh_fullscreen	0	Bool	[Todo]
nr_debug_light_mesh_volumesize_large	0	Bool	Only for debugging. Enable/disable new lights large mesh volume size mesh.
nr_debug_cull_deferred_lights	1	Bool	[Todo]
nr_debug_cull_deferred_code_lights_via_bsp	1	Bool	[Todo]
nr_dev_shoot_lights_enabled	0	Bool	Enable/disable point lights on each shoot. Only for player and only for bullet weapons. Shotgun can create several at once. Disappears after save reload. Warning:Kills performance.
nr_dev_lights_quality_override	0	Bool	Enable/disable light quality override. Required for some cvars with nr_dev_ prefix.
nr_dev_gb_debug_type	4	Integer	0 - DepthOnly. 1 - GBuffer_Fast 2 - GBuffer_Fast2. 3 - GBuffer_Fast3. 4 - Gbuffer_Slow.
nr_dev_gb_quality	2	Integer	Changes gbuffer quality.
nr_dev_lb_quality	1	Integer	0 is broken. 1 - default mode. 2 - debug materials with new specular.
nr_disable_setting_auto_reload	0	Bool	[Todo]
nr_fps_spam	0	Bool	For devolopers only. Spamming in the console performance values. Numbers aren't accurate.
nr_light_spot_bbox_optimizie	2	Intenger	Sets BBOX type for spot lights. Min value is 0, max is 3. There are note that 1 is broken. 3 makes BBOX size very small, so spot light sources will disappear even if they are in the player's field of vision.
nr_light_spot_mesh_volumesize_large	0	Intenger	This makes BBOX larger than it needs to be.
nr_lights_info		Void	Used by the game when you launch it. Prints in the console info about hardware support for texture formats, allocated formats and quality settings.
nr_lights_vol_check_threshold	10	Float	[Todo]
nr_light_settings_transition_exp	2	Integer	Affects the quality of the transition for changes from newlights_settings. 0 - no transition. 1 - transition. 2 - smooth transition.
nr_lights_procedural_disable_all_lights	0	Bool	Disable all proceduraly created new lights (npc_zombie_hev, item_battery, weapons, etc).
nr_lights_procedural_enable_lights_priority_check	1	Bool	If enabled - all the code based procedural lights will go through priority based check before adding to render queue.
r_nr_deffered_debug_normals	0	Bool	Enable/disable normals debug.
r_nr_deffered_force_diffuse_only	0	Bool	Forces new lights to use diffuse texture only.
r_nr_deffered_lights_hlslclip_range_on	1	Bool	Enable/disable actual new light range in normals debug.
r_nr_deffered_lights_hlslclip_dir_on	0	Bool	[Todo]
r_nr_deferred_AA_fix_multiplier	1	Bool	Fixes anti aliasing issues. Example. Disabled. Enabled.

Note:Work in progress! It's not full list.
