Octane materials normal in viewport, black in viewprt render

[tcoben]

I'm having an issue where if I try to export a viewport render to preview my scene, the octane materials are appearing black. They render correctly when I use the octane renderer, and they look normal in the viewport itself, but as soon as I use the viewport render option the octane materials render black. See attached image. Does anyone know why this is happening? I've rendered out viewport renders tons of times without issues, this just started happening recently. Also this does not happen for all my scenes, just some of them, and I am trying to figure out a solution.

Update to latest: viewtopic.php?f=85&t=80351
There is some new feature to load/generate the viewport textures with less lags and cache to load scene faster. And there was some problems until latest. Update it!

That worked, thanks so much!
