Thanks eyoli for your support. I am currently just using a hugely over-sized capsule for the character’s collision. Unfortunately, this means the character can’t fit through openings that are only as tall as the character, unless you modify the capsule size in realtime. You can use a smaller capsule to permit fitting through small openings, but then large appendages on the character will have no collision with static objects, even if you add additional collision capsules to these areas set to block all. However, this technique seems to work fine for blocking dynamic objects, but most of the environment must be made up of static objects. Not even blocking volumes can stop character penetration with the static world… only the single default capsule will do this!
I think Epic need not be afraid of implementing this change due to backwards compatibility. Simply make a separate, NEW character class that implements the adjustable collision or make a NEW character movement component that works with any class and keep the old versions in place for backwards compatibility.
