Can't find hit with btBoxShape objs using convexSweepTest

[zkunda]

I've searched forum for all night long.
When I add collision object which is a btBoxShape into btCollisionWorld, I can't get any hit using convexSweepTest().
But everything works great when I using btBvhTriangleMeshShape with the same object.
There's another post about the same problem, but no one gave an answer.

Please help?

Hi,

maybe you ran into one of those issues:

Thanks pico, but my code didn't fall into those situations.
I know that if I move one of the btBvhTriangleMeshShape in my collision world, I must call btCollisionWorld::updateAABBs() before I call btCollisionWorld::convexSweepTest(). But my capsule won't hit any btBoxShape in the collision world.

Oh god!
My client gave me a box size (10, 20, -20) and I haven't checked that.
Bullet uses right hand coordinate system when my engine uses left hand. Almost every vector3 value should be converted before sending to bullet. But !!!! SIZE value shouldn't be converted!

Sorry for my stupid mistake!
