@ydnar: q3map_nonplanar explanation from Remagen thread?

[rgoer]

Dear q3map2 jesus,

Over in BXpress’s Remagen thread you mentioned the following, about q3map_nonplanar:

That said, to make the bridge mesh more efficient, make sure it’s a shader like this:

textures/remagen/bridge_metal
{
	q3map_nonplanar
	q3map_shadeAngle 75
	
	surfaceparm metalsteps
	
	implicitMap textures/remagen/bridge_metal.tga
}

The nonplanar/shadeangle stuff will direct Q3Map2 to create a nonplanar mesh of the brush pieces making up the bridge. Also, make sure all the plain metal textured brush faces are unaligned in Radiant so they can mesh together more cleanly.

Would you mind explaining what you mean by “unaligned” brush faces? Also, what kind of efficiency gain could one expect to see from this kind of implimentation?

[ydnar]

By unaligned, I mean the same scale, offset, rotation on all textured adjacent faces. You can do this by selecting the texture in Radiant, and setting all the brush faces. This resets everything.
