# physics objects (triangle mesh vs triangle mesh) falling through each other

## physics objects (triangle mesh vs triangle mesh) falling through each other

Hi, I am a new user of SIO2 v 1.4.

I found a problem that two physics objects with triangle meshes (collision type) will fall through each other.

I did some experiments to make sure this problem:

(1) A cube with a cube by setting both of them as box collision types ---> OK to collide with each other

(2) A cube with a cube by setting one as triangle mesh and the other as box type --> OK to collide with each other

(3) A cube with a cube by setting both of them as triangle meshe collision types --> Fall through each other

(4) All other combinations are OK, too.

It seems only triangle mesh vs triangle mesh can't collide each other well!!

PS: BTW, i am using tutorial061/062 as my testing base project

thanks!!

Tim
