In my map I am trying to make a green opel truck (static/vehicle_opeltruck_green.tik) solid. However when I load the game you can walk through the truck. I have noticed this with several other objects too. However I know it is possible to make the opel truck green solid, because on the map obj/watten not only is it solid, but its textures include both wood and metal. How can I get a solid green opel truck into my map?
P.S. I am using MoH Radiant
Thank you!
