issue (?) in max 7 with spherical texture mapping

eriver's icon

Hi,
i have some trouble mapping on texture on a sphere in Max 7. I have a 3072x3072 texture wich is a peter's projection of the moon surface. In max 6, the mapping is ok (screen capture "max6"). In max 7, The mapping is distorded (screen capture "max7"). The patch is obviously the same (attached).
With a smaller texture (1024x1024) it's working well on max 6 and max 7. But i need a larger one.
Thanks a lot if you have any idea how to avoid this distorsion.
You can download the texture with its original size with this link:

hi eriver.
this is a strange one and i'm not sure what's going on. it has something to do with the AVF video engine though. this is used to read in the texture file, and obviously the large size is breaking something. fortunately there's an easy solution: simply change your default video engine from AVF to QT (Max Preferences -> Video Engine).
alternatively, you can use quicktime to load the texture without changing the application preference like so:

Great ! Thanks a lot Rob. It seems there's something with the file itself. I'm playing with different big textures of this kind. All Jpeg, standard size (1024 x...). Some of them are loading quiet well directly in jit.gl.texture and not with qt. Some other, as this moon, need qt... But now i have a solution for each of them. Thanks again.
