Hammer++/Bugs and limitations with unsupported games

This article or section needs to be cleaned up to conform to a higher standard of quality because:

grammar and layout

For help, see the VDC Editing Help and Wikipedia cleanup process. Also, remember to check for any notes left by the tagger at this article's talk page.

Black Mesa

Works with Source 2013 Singleplayer or Source 2013 Multiplayer version. However, there are some bugs and issues due to which you will not be able to work constantly.

New lights do not work correctly

Entities with "newLight_" and "newLights_" prefixes don't work with SmartEdit and attempting to replace an entity with one of these will cause a obsolete error.

• 

  A new light point placed with the Entity Tool.

• 

  npc_gman after being replaced by newLight_Point.

This is because new lights use capitalized letters in classname, causing Hammer++ to be unable to read them normally. You can fix it by replacing capitalized letters with lowercase in the FGD. However, you will still not have any preview for new lights.

Note:Similar issue with npc_xortEB.

Lightmapped_4WayBlend is not loaded

You will not be able to work with Xen levels and some Earthbound outdoor levels, since this shader is used for surfaces everywhere.

Workaround:Use the Hammer++ version for Counter-Strike: Global Offensive, as it is the only version of Hammer++ that supports Lightmapped_4WayBlend.

Note:You will need to port the game's assets because it doesn't use or support the old model format.

No surface blend preview

WorldVertexTransition was replaced by LightmappedGeneric in Black Mesa. This means that you cannot see blended surfaces in Hammer++, since this feature is not provided.

GRPortal is not loaded

Physics Tool doesn't work properly with new ragdoll entities

prop_ragdoll_original and misc_dead_hev are ragdoll entities, Hammer++ doesn't know about this.

Workaround:Add ragdoll() in FGD for these entities.

• 

  prop_ragdoll_original and misc_dead_hev simulating as "general" objects, in Hammer++ while prop_ragdoll works fine.

Strata Source

Mainly works with the Counter-Strike: Global Offensive version. Hammer++ will not provide features from Strata Hammer and the engine (mainly UI elements and how it works with content). The convenience of its usage will depend on what you plan to do.

Only supports the Counter-Strike: Global Offensive model format

Strata Source supports all model formats from any game. Hammer++ for Counter-Strike: Global Offensive only supports the model format from Counter-Strike: Global Offensive, so you'll need to port models if they do not use this format.

Workaround:Use the Source 2013 Singleplayer version

No Scale Override preview

Static props support the Scale Override keyvalue (similar to Source 2). You will not see changes in Hammer++.

Custom folder is not supported

Strata Source supports the custom folder. Hammer++ for Counter-Strike: Global Offensive doesn't.

Workaround:Use the Source 2013 Singleplayer version

Doesn't read mounts.kv

mounts.kv is a way for Strata Source to mount content from other games without editing the gameinfo.txt. Hammer++ doesn't read this file.

Escape sequences are not supported

Only Strata Hammer supports escape sequences.

Mapbase

Works fine with Source 2013 Singleplayer version. Some custom shaders may work incorrectly, and some custom features will not work as expected.

SDK_Cable doesn't work properly

Display skybox instead of a cable texture.

• 

  An example.

Spotlight textures don't apply to spotlight preview

Mapbase supports customization of the beam and halo texture. Hammer++ always draws the standard textures.

• 

  An example. Used obsolete icon for halo and electric texture for beam.

Left 4 Dead series

Hammer++ for L4D2 works fine on Left 4 Dead, except when compiling the map. After compiling the map and trying to join the map, an error will appear and display: STEAM validation rejected and after pressing ok, the menu will be frozen.

In Left 4 Dead 2, the same error happens but without the Steam rejection, only displaying multiple repeating errors (C_CL4DGameStats: failed to download stats from Steam, EResult 2) on console and unable to interact with the menu.

Fix:Remove the steam_appid.txt from the hammerplusplus folder.

Textures glitching on Displacements

In Left 4 Dead 2, textures glitch on displacements when the camera view is far away.

Workaround:Disable the Displacements VisGroup.

Skybox texture glitch

This only happens when you have env_sun in the map.

When looking at the skybox texture with other textures (e.g. tools/clip), entities, etc. The skybox appears normal, when only looking at the skybox texture without looking anything in the map, the texture changes to a sprite texture, which is sprites/light_glow02_add_noz.

Workaround:QuickHide the env_sun.

Also, while looking at the skybox with the sprite showing or looking somewhere in the map and having the Texture tool shown or the "Current texture" on the right side, when minimizing Hammer++ and then going back, the "Current texture" or the "Face Edit Sheet" will take a top left corner screenshot of the 3D view port and replace the image where the texture is supposed to be at.
