In the changelog for blender 2.36 it says that Yafray got support for more types of blender textures. However, I still can not get musgrave, voroni, or other to work properly. Is this an issue that just comes up for us linux people?
I asked this as well when it came out. The short answer is that these are still not supported.
It seems that it isn’t in the official build for linux, but I built Yafray from CVS and, well this is what I got.
That the ridged multifractal musgrave on a distorted noise texuture. Woot!
Although interrupting yafray with the ESC key doesn’t work as well, it’s still worth it for this.
