New Translucency Details

	It's possible to put the lit texture on one side of a brush and the unlit on the other and have both work, so windows could have the proper appearance depending on whether you are looking inside or outside.		It's possible to put the lit texture on one side of a brush and the unlit on the other and have both work, so windows could have the proper appearance depending on whether you are looking inside or outside.

			== New Findings ==

			Real Translucency

			Rich_is_Bored discovered that a technique for translucent lighting discussed on Polygon forums could be implemented in Doom 3
			by setting the vertex color gray and using an inverted normalmap for the inversevertexcolor.

			Rebb found that you could use the scale keyword to programmatically invert the normalmap.

			Finally, Rich_is_Bored found that all surfaces can use the effect if you simply set the diffuses stage to rgb 0.5
			which is essentially the same as gray vertex color.

			Final example:

			<pre>

			translucent/example

			{

			// first pass

			{
			blend bumpmap
			map normalmap.tga
			}
			{
			blend diffusemap
			map diffusemap.tga
			rgb 0.5
			}

			{

			blend specularmap
			map specularmap.tgs
			}

			// second pass
			// the scale function here is "inverting" the normal map so that it catches light from the opposite side.

			{
			blend bumpmap
			map scale(normalmap.tga, 1, 1, 0, 1)
			}
			{
			blend diffusemap
			map diffusemap.tga
			rgb 0.5
			}

			// TDM Ambient Method Related

			{
			if (global5 == 1)
			blend add
			map diffusemap.tga
			scale 1, 1
			red global2
			green global3
			blue global4
			}

			}

			</pre>
