G'day. I'd give detailed help on this but I'm currently in military and unable to access any of my files or similiar. But I'll try to give some pointers..

How about simply increasing the ambient lighting of the ground triangles affected? Same would go with affected units. > The third thing: I can get the mouse coords translated to 3d coords, but > I have to supply a z coordinate.

Not sure why you would want to do this, z is depth, 2d coords don't have depth, so you can't affect it by moving the mouse. Mright, gotta run now. Welcome aboard anyway! snaip _______________________________________________ Soya-user mailing list Soya-user@gna.org https://mail.gna.org/listinfo/soya-user
