Mtl Editor Slots all black?

We are having a problem that only recently presented itself. We installed Vray 1.5 RC3 32 bit for Max 9 when it first came out. We have been evaluating several projects in Mental Ray, but are using Vray for this particular project. When we switched Vray on we got a very strange result in the material editor. This happens on all our machines even with a clean reboot and fresh scene in Max. We switch to the Vray renderer, and open the Material Editor. The slots take several minutes to refresh, and all look like this. . . .

and if I unlock and switch the mtl editor to scanline I get a very familiar result . . .

Any ideas? Thanks.

If the UI is set to a Mental Ray preset, this can happen. The mat slots are
preloaded with Arch&Design mats. I have had this problem recently.

Re: Mtl Editor Slots all black?

What happens when you try and do a regular rendering with V-Ray? This effect can happen if for some reason V-Ray cannot find a license. If you do a regular rendering, you will get an error in the V-Ray messages window in that case.

Bingo. Our licence server had crashed. Vray was not finding any licences. I have gotten accustomed to solving bizzare glitches with MentalRay. I miss the reliability and simplicity of Vray. Thanks Vlado.

mmikee - that was a good suggestion, thanks for responding so fast.

Great supoprt from the Vray Forum, another plus for Vray!!!

how can my material ’ when i open Material editor for a new project ’ can be all Vray material instead of architectural.

I have seen a way to configure it , but can’t find it anymore.

any clues?
