Everything in my project still works except when my character walks on mesh colliders now he bounces.
Thats it. Everything else works.
Box colliders are fine, terrain colliders fine, but when my rigidbody character with capsule collider walks on mesh collider he bounces.
I check all the obvious stuf like physics materials etc. I even tried adding physics materials with no luck. I have tens of thousands of objects with mesh colliders in my game and I would like to be able to walk on them does anyone have any ideas?
This is not enough information for us to reproduce the issue and to help you in any way. There is a huge amount of possible causes for that problem. It would be necessary for us to get a small reproduction of the project with at least a minimized character controller and a few colliders, such that we can help you.
but the project works fine in 3.5. whats different with the collider system in 4.3? and when you say there is a lot of causes for this i dont think thats correct. i think this is something very specific. are you saying its something in my project thats causing it? well im taking it there is no new physics feature or anything that is causing this, maybe it is in my code. i dont know. thanks anyway.
well i finally figured it out. rigidbody had something called collision detection and it was set to continuous. in the older version of unity this did nothing obviously since the same setting caused no bouncing in 3.5. thanks to all who tried to help.
There are tons of small changes happening in the background between updates and especially major updates. It is almost impossible for anyone to understand what is going on without having access to the project or even better to a small reproduction.
