  uv-mapping - what am I doing wrong?

Hi all,

I want to uv-map a little bird-model as some would already know. Everything
worked well at first:
I took the bicubic_patches, added the uv_mapping-keyword to each of them and
painted a image_map for them. I applied the image_map to the whole union
patches.

Looks good, all is fine - until I rotate the model around the y-axis. If I
do so, the texture does not rotate with the model. Scaling works,
translation works. Rotation around the z-axis works. Rotation around the x
or y axis does not work (which must have to do with the fact that these axis
are mapped on the u,v coords).

Is that the correct behaviour? Is it because I applied the texture to the
union, not the individual patches? Is there another solution than rotating
the texture as well?

Thanks for your help,

Marc-Hendrik
