The spoiler I made has all the models from L0 to L3.
I made the collision in this way: I drew a box shape from shapes menu (the one with capsules, spheres, cones etc.), scaled the box to fit the spoiler. and converted the box into a COL state.
I added the '116' flag to the spoiler COL selected beforehand, according to this tutorial:viewtopic.php?f=31&t=7349
but it still doesn't draw bullet holes. What do I do?
