View Full Version : OpenGL slowwww rotating model in texture view

Hi all.

I have had an issue in modeler for awhile now with models exported from Poser.

In modeler, with view mode set to texture, and a single viewport, simply rotating the model would cause huge OpenGL lags.

The models are approx. 200K polys, with many non-planars (but that's another story). :-)

The models use huge (4096x4096) UV texture maps.

So, I tried removing all the textures as a test and saving to a temp model.

Viola, OpenGL rotation is wicked fast (I have a GTS250 1GB).

So, next I added textures back onto the model, one at a time and found the issue! If I add the transparency image maps to the model, OpenGL performance goes back in the toilet.

I have 'Transparency' and 'Transparency Channel' un-ticked in the GL tab of the display options.

Anyone ran into this? Workarounds?

Thank you for reading.

Replied in the other thread. BTW, the French is "voila" (or voilą if you want to be really correct). ;)
