Grass on lightmapped terrain (SoF2)


Recommended Posts

Hi, I'm having an issue with getting foliage on a lightmapped terrain for Soldier of Fortune II - Double Helix ( the engine brother of JK2).

 

It shows up on some small places but not spreaded. If I use vertexlit terrain, then it works like it should but the lightning is then bad.

 

shader:

textures/riverpass/terrain_base

{

q3map_material LongGrass

q3map_lightmapsampleoffset 8.0

q3map_lightmapMergable

q3map_lightmapaxis z

q3map_tcMod rotate 37

q3map_tcMod scale 1 1

q3map_tcGen ivector ( 512 0 0 ) ( 0 512 0 )

q3map_nonplanar

q3map_shadeAngle 120

}
