Latest win64 build on windows 7 doesn't show the material preview the right way.
Only vertical stripes apear on textures.

Re: vray material preview problem

Hi once again,
My vray version is 2.0
Dont know if it helps triger the issue, but when I select blender render it does not have any problem showing textures.
This happens with 2.61.0 version 42627

No problem before on 36380

Thanks in advance.

ThanKs, but don't worry too much about it.
It's just a preview without any consequences on renders.

Oh, one more thing, but this time is a very nice bug!

I was testing caustis and I have seen that you kept "TODO" on the alt text that comes up when we play with search distance and max photons.
But it works! And is so cool playing around with them!
It's cool to find out that we must erase some things from the todo list isn't it?

Re: vray material preview problem

I have a problem related to this, so I think it's a good idea having same problems all together.

I just updated blender and exporter and all is working fine again, no shutdowns, new Bmesh working fine too, but now I have no material preview.

This is the terminal output:

Re: vray material preview problem

Ok, Andrey, it's important, I'm doing a work that I have to finish tomorrow and it's a bit difficult to configure the materials without preview them.

Thanks.
