Gabriel, I never had any problems with getting the viewports working. Have you tried both D3D and OpenGL?
Yes. Both work fine with an empty scene. As soon as I load in my animated model and turn the Ogre Preview back on again, boom, it goes black and Max locks up.
I have max8 in D3D which is a lot faster than GL, and it's never failed to work yet. My video card is a 6600GT 128mb AGP with forceware 84.25 (the oblivion ones).
Yes so do I. Exactly the same card and drivers. Perhaps it's a Max 7/8 thing then. I'm not paying for a Max8 upgrade I don't need, so I'll try the OFusion forums, thanks.
