terrain lighting oddity

(evillair) #1

Is there something I can do to fix this?

I have this problem in random places in my map.

It doesn’t get fixed with a full compile + bounces.

Post your terrain shader(s).

It looks to be an alphamap bug rather than a lighting bug, anyway.

Here you go…

Take

q3map_lightmapMergable
q3map_lightmapsamplesize 256
q3map_lightmapaxis z
q3map_tcGen ivector ( 234 0 0 ) ( 0 234 0 )

Out of each shader except the base. The other shaders should inherit it from the base shader.

Put:

q3map_baseshader textures/flakcannon/terrain_base

in each shader if it’s not all ready there…

Awesome, thanks hummer, worked great.

The shading is alot nicer too.

Thanks again.
