I basically have the character controller and a BvhTriangleMeshShape object that is the static geometry in the scene. This assertion seems to happen when I use setWalkDirection of the controller. If I use setVelocityForTimeInterval then everything works fine for normal movement. The only issue with this method is jumping since the velocity is reset to 0 and gravity wont be taken into account until the new velocity vector is not 0, i.e. the next time a movement is action is received from the user.
Has anyone run into this before? Everything runs fine on OSX. I don't hit the fuzzyzero assertion when using setWalkDirection. It is only happening on my Windows build. Below is the stack trace. Thanks for any help.
