None Rendered Barrier?
I've noticed a weird problem in some of my worlds. Collision detection just doesn't work quite as well when moving backward.
For example, I have a open window. If I try to go through it forwards or even at an angle, I'm stopped every time. If I go backwards, I go past 50% of the time. It is also a problem with more complicated meshes.
My solution was to add a simple polygon planes or boxes around problem objects with a transparency of 100%. It works, but now it is rendering slower due to the transparency. Is there anyway to mark a node as "use for collision" AND "don't render"?
