Re: Quake Iv?
"The X-ray DX9 render actually will have unified lightning just watch some of the DX9 indoor demos."
I actually don't know anything about the X-ray engine, but if you need DX9 level shaders to do unified light and shadow, you aren't as cool as the D3 engine, which can do it on anything with a stencil buffer. That's not to say that the D3 engine is actually superior to the X-ray engine - for all I know it's not. It's just that if you do need DX9 level effects to pull off your lighting scheme, your engine probably isn't as versatile as the Doom 3 one. As I say - for all I know the X-ray engine doesn't need DX9 to actually do the lighting, I'm just basing it on your post.

Ridiculous DOES not have an 'e' in it. It comes from "ridicule" and has less than nothing to do with the colour red.
