Inputs

TurnOn <void>

Turn xog on.

TurnOff <void>

Turn xog off.

BaseTrigger

Toggle Toggles this trigger between enabled and disabled states. Enable Enable trigger Disable Disable trigger TouchTest  (in all games since ) Triggers either the OnTouching or OnNotTouching outputs for whether anything is touching this entity. Bug:Sleeping prop_physics will never fire "OnTouching". Also applies to entities using prop_physics as base.  (tested in: ) StartTouch  (in all games since ) !FGD Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities. EndTouch  (in all games since ) !FGD Behave as if !caller had just exited the trigger volume. DisableAndEndTouch  (only in ) Disables this trigger and calls EndTouch on all currently-touching entities.

Outputs

BaseTrigger

OnStartTouch !activator = entity that caused this output !caller = this entity Fired when a valid entity starts touching this trigger. OnStartTouchAll !activator = entity that caused this output !caller = this entity Fired when a valid entity starts touching this trigger, and no other entities are touching it. If there are any other entities touching the trigger when a new one begins to touch, only OnStartTouch will fire. OnEndTouch !activator = entity that caused this output !caller = this entity Fired when a valid entity stops touching this trigger. Note:Will also fire for entities touching it when trigger is disabled via Disable input Warning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid. Warning:OnEndTouch can fire before OnStartTouch under certain circumstances[How?] where both are fired on the same tick and each have the same delay. Fix:Add a slight delay to OnEndTouch. OnEndTouchAll !activator = entity that caused this output !caller = this entity Fired when all valid entities stop touching this trigger. OnTouching  (in all games since ) !activator = !caller = this entity Fired if something is currently touching this trigger when TouchTest is fired. OnNotTouching  (in all games since ) !activator = !caller = this entity Fired if nothing is currently touching this trigger when TouchTest is fired.

Issues

Xog incorrect work with $translucent

Xog all time fully rendering through everything with material shader parameter $translucent. This happen because of game can't tell the depth of scene because of the transparency.

• 

  No $translucent. Behind the wall placed xog volume and some models with small room.

• 

  With $translucent. Now player see everything, but only what in xog.

Similar issue happen if use $alphatestreference incorrectly.
This problem also applies to brushes which not have $translucent, but which parented to brushes that have this parameter. Similar will happen if brush with $translucent is part of your brush entity. Same will happen if you use overlays/decals on brushes with $translucent.

• 

  Metal speaker is overlay that use $alphatest, but xog fully visible anyway, because overlay pasted on the transparency window.

This issues does not happen if replace LightmappedGeneric to ShatteredGlass or UnlitGeneric, so, you can use one of them for glass or transparency surfaces when it's needed.

• 

  LightmappedGeneric.

• 

  ShatteredGlass.

In some cases use $alphatest if it'll give similar to $translucent resualts.

---

Xog incorrect work with $alphatestreference and $allowalphatocoverage

$alphatestreference is a material shader parameter that specifies the threshold alpha channel value at which the surface should be transparent instead of opaque, default "0.5". $allowalphatocoverage creates translucent steps based on alpha values. Both have one and same problems with deferred lighting. For examples used this texture with this alpha channel.

• 

  Diffuse texture.

• 

  Alpha channel.

Here xog placed behind wall with the texture. We can see the circle part of that have alpha channel part which is invisible due to $alphatest, with enabled xog we see that the invisible part doesn't show through itself deferred lighting with shadows.

• 

  Xog volume disabled.

• 

  Xog volume enabled.

If use very low numbers you will see resualts like in the pictures.

• 

  Xog volume disabled.

• 

  Xog volume enabled.

You can't escape this problem, only minimize effect with $alphatestreference 0.1 or if paint alpha correct channel.

Motion blur blurring viewmodel xog layer

For some reason Motion blur blurring viewmodel xog layer, you can notice this when you just rotate camera. This issue happen even if xog behind other objects.

• 

  An example.

---

Xog incorrect work with -tools

If you don't use Full Screen - xog will incorrectly applying to screen.

• 

  An example.

---

Xog volume doesn't work with 3D Skybox

Don't use xog volumes in your 3D skyboxes, none of them will work at all.

• 

  An example. We see that xog volume works fine, but 3D Skybox don't draw it.

---

Xog doesn't refract by refract shader and fully draw through

Unlike deferred lighting, xog doesn't refract by refract shader, also fully draw through.

• 

  An example.

If model with refraction behind wall with refraction - this cause issues like this.

• 

  The magnifying lamps behind the wall with refraction. This wall doesn't show magnifying lamps to escape issues, but xog break this.

Similar issue with cloak material shader parameter.

• 

  An example with npc_human_assassin.

---

Xog volume atrociously work with Linux and Linux based OS

Xog volume flickers and draws through all object (with exception of viewmodel) on Linux. Linux port is atrocious. The only thing that can help is Proton. The only platform that works fine with Black Mesa is Windows.

Confirm:Does something like this happen with newxog_global ?

Weird issue with refracting water

If players camera hit refracting water - surface models become translucent.

• 

  Players camera doesn't hit the water.

• 

  Players camera hit the water.

Similar issue with underwater models if players camera doesn't hit refracting water.

• 

  Players camera doesn't hit the water.

• 

  Players camera hit the water.

Confirm:Is there a way to fix this and don't remove refracion from water material ?
