I’ve just started learning Unreal Engine (I’m still pretty new to 3D game development in general), and was trying to figure out how to utilize a mesh designed in Blender as a level. I came across this page which seemed to answer my question about how to make collision geometry in a modeling tool. The page says that “In the case of an object whose collision is defined by multiple convex hulls, results are best when the hulls do not intersect with one another.” Why is this? If I am making collision geometry in Blender, is it true that adjacent collision meshes must not share any vertices (or overlap)? I would have thought it would be bad to have gaps between collision meshes. What are the consequences of overlapping collision meshes? If a gap is necessary, how much of a gap is recommended?
Thanks in advance!
