Progblog is actually late because I decided to combine it with a Blender notes and it took the better part of forever x_x
Make a collider. Some people do it by decimating a copy of the character. I made one by my old Blender retopo method of edge modelling with mirror and shrinkwrap modifiers (which took way, way, way longer than it should have because I kept stopping, procrastinating and whining all the way through it, much like my children with the much hated bookwork) and remembered why I bought 3d Coat. I did that rather than decimating so the collider would have no facial features aside from hints of eye sockets and a nose bump, and no digits, so it could be super low poly and the right shape (this one is not really super low as the head and hands are a bit dense).
