When I try to put one of my own projects in the bootcamp demo terrain it just falls, it does not collide with the terrain. What can I do?
Make sure the object has a rigid body attached. Also, check to make sure the terrain has some sort of collider attached. A mesh collider or a simple box collider should work. Another thing to check is that your character is fully above the terrain when you spawn them, if he is barely clipping the plane this can cause him to fall through.
thats the stupidest anwser ive seen so far, it obviously dosent have a mesh applied.
