Hello

I have some questions about 3D stuffs i would like to do.

1) How can i create an object box that always fit the width and height of the Screen ? (even when i resize it)
2) I have a 3D dice with a size of 0.8, how can i fix his pivot at his center ?
3) How can i get the local angle X, Y & Z of this dice ?
4) When i use 3D physics, the SetObjectPosition seems to be not working. Should i do something to change that ? How should i proceed ?

I've made dices that you can throw, but once they touch the ground, SetObjectPosition don't seems to reposition them at their start position.

Okay, i've just tested first if all the dices have hit the table.
And after, i've just compared the old and new angles values : when nothing moves, the angles are the same.

Thanks a lot
