Losing UVs on render

[elpin]

We are using Power Nurbs Viewer 8.0 to render nurbs objects imported from CATIA and we have a problem that some nurbs objects with applied UVW mapping modifier acts like there are no UVs at all. In the viewports the map looks okay, in the preview render also and then when we go for hires render the UVs are suddenly lost and the only way how to get them back is to close 3dsmax and reopen the scene again and render right away. Then all is fine... usually. Sometimes we have to reload the scene twice. Reapplying the UVW map modifier doesn't help, only reloading the scene.

Any help would be appreciated. Maybe it was fixed in next releases? If so, would it be possible to get a newer Viewer software?

Thanks!

Hi David,

There are some weird updating issues with the Pwr_Unwrap. Usually disabling/re-enabling the unwrap will get it to update (I usually just double toggle the light-bulb icon on the modifier stack). But, for this case, if re-applying the mod doesn't work, I'm guessing disable/re-enable also doesn't?
