Material preview not available while rendering

[MLalakStudio]

Dear Users and CG Team,

I'm pretty new user to V-Ray 3.6 (after upgrading from 2.0) and day by day I'm even more frustrated... But maybe this one id just a bug or some wrong setting (hopefully). So the thing is that material preview window goes black while render runs. It means that I'm unable to check other materials (their V-Ray appearance) while rendering which actually slows my work dramatically! I'm froze while rendering!

Previously (v2.0) I was able to do my normal work with Sketchup or even use two V-Ray processes at the same time (on two different Sketchup projects). Now I'm stuck!

Please help!

Cheers,
Marlena

Here is what I mean with this preview...

Does this occur with specific project or even newly created ones?

Are the filepaths of the bitmap textures valid? You could use the File Path Editor to check if there are any missing texture (Extensions > V-Ray > File Path Editor)

Hello Georgi,

Thank you for replay. Yes - it happens every time I start render. Paths are definitely OK and everything works fine when not rendering at the time. Please let me know how to deal with this issue because it is unacceptable for me to have this preview unavailable...

Cheers,
Marlena
