User:SirYodaJedi/Source map compiler wishlist

Features I'd like to see in custom compilers for , , and

BSP / CSG

• Everything from Mapbase's VBSP
• Generate a file alongside the BSP (or in the zip lump) containing KVs for func_group, func_detail, and prop_static, for use with VRAD.
  • The brushes would be stored as a comma-delimited list of brush numbers, indicating which brushes are in the group.
  • KVs which are used by the static prop lump are stripped, along with targetname, mindxlevel, and maxdxlevel
• func_group
• Ability to set func_group and func_detail as nonsolid (ex: for foliage), disabling generation of brushsides for the given brushes.
• Ability to override the contents of func_group and func_detail (ex: for grates).
• Ability to set DeathByNukes's (also in ) %compileChopHigh, %compileChopLow, and %compileChopAll settings directly in func_group and func_detail's KVs, so that the same material can have different chop settings in different situations (improving runtime performance)
• Ability to toggle Quake II-style detail brush behavior for func_detail (in a KV), wherein it still chops underlying world brushes, even though it doesn't affect VIS. This fixes some lighting bugs caused by the world brush lightmap bleeding underneath the func_detail. You can manually do this with nodraw brushes on stock compilers, but that eats up more brushsides.
• func_illusionary_visblocker - A world brush that blocks vis but is non-solid.

VIS

• Rename vvis_dll.dll to allow installation alongside vanilla compilers.

RAD

• Rename vrad_dll.dll to allow installation alongside vanilla compilers.
• 64-bit executable, regardless of whether engine is 64-bit
• bounced prop_static lighting (bouncing both ways between props and lightmaps); this would be really beneficial on lightmapped props
• Ability to select texture format for PPL files:
  • Recommended formats to allow:
    • RGB888 (default), RGBA16161616F, DXT1, I8, BGR565, BGRA8888 (RGBM-compressed HDR), DXT5 (RGBM-compressed HDR)
    • BC6H (default), BC7, RGBX8888, RGBA8888 (RGBM-compressed HDR), RGBA16161616F, DXT1, ATI1N, I8
  • This could possibly be noted by using lightmap resolutions higher than 4096 (reading the three most significant bits as a separate value, with 0 being the default RBG888).
  • Alternatively, unused static prop flags could be used, but VBSP would need to be modified to properly write them.
  • Or just use the extra data I suggested writing in VBSP.
• _nobounce KV on lights, which disables bounced lighting from the light source.
• _nodirect KV on lights, which prevents direct lighting from the light source from being written to the lightmaps.
• _nodynamic KV on lights, which prevents the light source from affecting dlights.
• bounced named lights (could also have radius-based control over how far they are allowed to bounce)
• toggleable shadows for brush entities, handled in a similar manner VHLT's light_shadow (so they'd be controlled by a regular light entity in-game)
• toggleable texlights, handled in a similar manner VHLT's light_surface (so they'd be controlled by a regular light entity in-game)
• %lightmapmask for VertexLitGeneric, which dictates locations of the PPL lightmap to mask out and replace with a dialation fill like xwad does for index 255 of transparent textures.
• An equivalent to ericw-tools's -dirtdebug command, which disables standard lighting and only puts generic ambient occlusion on edges to prevent the unsealed fullbright map from looking bad.
• Colored texture shadows.
• Texture shadows from Refract materials.
• _minlight on prop_static, func_group, and func_detail
• _maxlight where _minlight is available
• _minlight_color and _maxlight_color, which control the color of _minlight and _maxlight
• Half Lambert flag for per-vertex and lightmapped static props
