Thanks, that's very helpful. Now I have a texture with an in-circle pix,
and that texture is mapped into a polygon.

However, the result is a bit weird. It looks like the point of view is
rotated by 90 degrees and with a bit angled Z-axis. I don't understand
the camera object. How can I get back to something more frontal ?

Cheers,
