i have trouble with some thigs:
- the physics cube seems to behave different to the gl cube; any pointers on why?
- how can i realize a 5x5x5 grid in this style?

thanks for any help!

check out the phys.multiple help file. it contains a 4x4x4 grid of shapes.

lastly, if you connect your phys.world to your gl.render, instead of the other way around, your phys.picker will work properly.

if i do the changes you proposed, it seems like the rotation matrix of the cubes get twisted once i let them collide – is there a way to reset the rotation for all cubes?

thanks.
