Hi! Well, my rigidbody2d's collide fine as long as they have circle colliders. If they have box/polygon colliders, then they seem to be fine until in some tilemap sections they can suddenly go through the edge and pass to the other side of the edge. But it only happens in some (unknown to me) circumstances. It is not as common as it could seem reading the post.
It is true that if I disable tk2d edge optimizations, with more vertices over the edges, everything goes fine again. So it made me think of scales and so, but I had no luck tweaking things.
I have set "20 pixels per meter" in TK2D. The leading object in my game, a ball, has a collider radius of 1.46f. The objects that show the issue (the biggest ones: some brick-like boxes) are 3.2f x 6.0f. Do you mean they could be scaled too big for Box2D?
Thank you in advance!
