Quad meshes are fine.

Still, if I need an x or z axis cylinder, I just build one on y and rotate it, right?

I dont need to save my Maya with everything on y-axis? Tests seemed ok but I needed a confirmation. Also I needed confirm that if I build it straight on x axis, it is bad. This is related to imported colliders.

This because sometimes my colliders dont work for unknown reason. Not to add at some point the items crash the game and the only way to solve was to reunpack. But this is anorher concern.

Yes the cylinder needs y-axis orientation for the mesh. Also the mesh needs to have its center at (0,0,0).

Use freeze transformations and moving the pivot to (0,0,0) to achieve this.

Thanks xpadmin

Freeze command really kicked my maya and xsp knowledge on a new level.
And my colliders really started to work as they should. Im thinking on how to complicate them more:) and keep their interaction ok.
