Standard detail texture procedure

[fromhell]

For best result (and fastest for the renderer's multitexturing path), have the detail stage AFTER the lightmap.

If you use q3ase to build shaders, ignore its warnings about the detail layer. It knows nothing.

For example:

Code:

textures/base_floor/clang_floor
{
	surfaceparm metalsteps
	{
		map textures/base_floor/clang_floor.tga
		rgbGen identity
	}
	{
		map $lightmap 
		blendfunc filter
		rgbGen identity
		tcGen lightmap 
	}
	{
		map gfx/fx/detail/d_met.tga
		blendfunc gl_dst_color gl_src_color
		rgbGen identity
		tcMod scale 8 8
		detail
	}
}

Yeah, now I have to go back and fix a lot of my detail shaders. OA has so many textures to stick a detail on this is going to take a while, and some i'm not even sure what material to use (i.e. slimefac's abstract patterns).


Grates, and other alphatest stuff

Don't forget your depthFunc equals on the detail stage

Code:

textures/base_support/x_support
{
	surfaceparm metalsteps
	{
		map textures/base_support/x_support.tga
		rgbGen identity
		depthWrite
		alphaFunc GE128
	}
	{
		map $lightmap 
		blendfunc filter
		rgbGen identity
		tcGen lightmap 
		depthFunc equal
	}
	{
		map gfx/fx/detail/d_met2.tga
		blendfunc gl_dst_color gl_src_color
		rgbGen identity
		tcMod scale 8 8
		depthFunc equal
		detail
	}
}
