kk i found a blend file on a fileshare site somewhere, anyway it has three vases, when i render it with the internal render i get this:
kk so my problem is 2 things:
there appears to be distortion in the pictue (not sure what its called… Dispeckling?)
when i try to render using Yafray it renders the three vases white, gray and black!
I think Yafray works with all Blender’s procedural textures now, but those look like they’ve been mapped with images - make sure you use image formats that Yafray works with (I think it works with TGA, but I might be remembering wrong).
I found this in the Yafray FAQ, which says that packed textures don’t work unless you unpack them to a directory. Since you downloaded the blend file, my guess would be that that’s the problem. To unpack them, you just push the little ‘unpack’ button (in the UV editor or in the Texture pane of the Materials window, depending on how the textures are loaded) and it should save them to a path relative to where your blend file is.
