Hair material renders black

[twinmold]

That's pretty much it; whatever the settings, the Hair material just renders opaque black. Is it still WIP?
I'm using the latest available custom build and VRay for Maya 2011.

This could be if your vray is not the latest, this material could be just unavailable in your vray build.

Dunno what to tell you. I tested it again at work this morning with a standalone 2012 x64 build, with the same results. It happens both when I apply the material to a mesh with or without particle system (see attachment)

Check blender console if there are some error messages.

Re: Hair material renders black

My hair material renders black as well. I've trying different settings and operation system (Windows Xpx86 and Windows7 x64). Also materials preview renders black, there are no errors during render, Oh and my vray core is 2.00.01.

PS. I've found out that forum isn't accesible from vray.cgdo.ru link is directing to http://cgdo.ru/ and I'm getting Permission issues

Re: Hair material renders black

Yep, this warning mean your vray doesnt support hair material. URL works fine for me, anyway I've added some dummy page on cgdo.ru.
