Detail textures in 
GoldSrc are textures that are overlaid on a WAD texture to increase the perceived detail of the surface, without increasing texel size (which would result in using up more AllocBlock).
Unlike Source, detail textures in GoldSrc always use DecalModulate, and are always 24-bit.
Important:Don't rely upon detail textures for a map to look "correct"!Users whose GPUs have blocked the GL_ARB_multitexture extension (such as for 
enabling overbright lighting) will not see detail textures.
Bug:Detail textures may not work using the native 
Linux binaries. (relevant issue on GitHub)
[todo tested in ?]
Bug:Detail textures may not work properly on non-power-of-two textures. (relevant issue on GitHub)
Workaround:Pad or rescale the texture to the next power of two.Workaround:NOT RECOMMENDED Disable mipmapping, by setting gl_rendermode to GL_LINEAR (bilinear texture filtering) or GL_NEAREST (nearest-neighbor "unfiltered" textures).
Warning:This will cause noticeable shimmering on distant textures when in-motion.{{note|Detail textures can only be used on BSP and WAD textures. To allow more detail to be added to an MDL texture, use a higher resolution (up to 512x512) canvas, as MDL textures aren't subject to AllocBlock (since they aren't lightmapped). UVs can also be realigned to use more textures, if a 512x512 canvas is insufficient.
Tip:Use 
Half-Life Asset Manager to enable mipmaps for such high-resolution textures, in order to greatly reduce shimmering on the textures when at a distance.
