Use clipping with lod if u dont already
example
Code:
action Object_ClipAway(){
  my.eflags |= CLIP0;   // clip away at 50% LOD range    
  wait (1);            
  my.emask &= ~DYNAMIC; // then make entity static for better performance	      
}
action Tree_Wed(){
  my.eflags |= CLIP0;       // clip away at 50% LOD range    
  set (my, POLYGON);        // if grass PASSABLE of course
  my.skill41 = floatv (30); // values for animTree
  my.skill42 = floatv (30);
  ent_mtlset(me,mtl_animTree, 1);	
  wait (1);
  my.emask &= ~DYNAMIC;     // then make entity static for better Performance
}
