Is the material preview not functional in the demo?

[pacificdoc]

Hi everyone,

I've installed the latest version of Vray for Blender, but I can't get the material preview option to work. The standard render works fine, as long as I'm within the resolution limits (600 x 450). Is this normal for the demo version? I'm using the Maya Standalone Demo. Thanks in advance.

This must be a bug, but anyway viewtopic.php?f=8&t=703.

I confirm. No material preview, just a black screen.

I´m using the latest Demo V-Ray for Maya 2013 64bit on a Mac OSX 10.8.
V-Ray Standalone DEMO, version 2.20.01 for x64 | V-Ray core version is 2.00.01

Since the Demo of V-Ray for Maya2010 32bit is outdated on my system I can´t tell if it works with the 32bit version. Although the render feedback works nice I´m really missing the VFB. The limitations of the V-Ray Demo makes it a real PAIN to test!

@ehsan_wwe and @pacificdoc:

Please share which V-Ray Demo versions you are using and which system you´re on. We need to find out which setup causes this problem.

Sure, but we need to help him to understand which system setup we´re using. That´s crucial and that´s why he referred to the "Bug Report Rules" in his first reply. Since you´re a programmer too you will likely know how important such additional information can be. For example: it makes a big difference on a Mac whether you´re using V-Ray in 32bit or 64bit.

don't hurry my friend

I´m just trying to avoid wasting bdancers time.

go to system menue and select console windows
delet material and create a new material

On a Mac there is no such option in the system menu. I get all debugging infos when I launch vrayblender from the command line. So when I create a new material I prints out this:

V-Ray/Blender: Writing scene...
V-Ray/Blender: Writing frame 1...
V-Ray/Blender: Writing frame 1... done [0.01]

The result is always the same: just a black screen in the material preview.

do you see render ?

Rendering the scene works, although I don´t have a VFB since I´m using the 64bit Demo on a Mac.

I had the same problem when I point blender where is vray by hand. You have to make system link in mac and ubuntu, as well as let blender find vray by itself in windoes.

Thanks for the hint witaj. This solved the problem for me. Just like you I´ve manually set the path to the vray binary. After creating a symbolic link in /usr/bin/ and changing the Exporter to "Detect V-Ray" it worked.

Thanks.
