a little tip: setting vertex normals to point upwards makes lighting of grass models more uniform, and look much better when the camera moves around (I added this quick feature to MapBuilder a few minutes ago)



Code:
void Grass_SetNormals(ENTITY* ent)
{	
	int i;
	for (i=1; i<=(var)(ent_status(ent, 0)); i++)
		{	
			CONTACT* c = ent_getvertex(ent, NULL, i);   	// vertex number begins with 1 !			
			
			c.v.nx = (float)0; 		
			c.v.nz = (float)0; 				
			c.v.ny = (float)1; 				// upwards - uniform lighting

			
			ent_setvertex(ent, c, i);
		}
}


another tip: for tree leaves I use an modified central normalization. more exactly, normals got by lerping 2 values: the vector pointing out from entity middle to the actual vertex, and its original normal vector.
