Weird image-texturing problem (layers)

[elven]

Hi,

I recently stumpled over a weird problem that I can't seem to solve without some help...

I'm using Yafray for rendering.
Now, let's say - for simplicity - I have three objects in my scene:
* object 1: image texture A
* object 2: image texture B
* object 3: image texture B

Scenario 1:
Object 1 and 2 are together on one layer, object 3 is on another layer that's not visible.
Render... Object 1 has a texture, object 2 not (base color showing).

Scenario 2: All objects are on the same (visible) layer.
Render... Both object 2 and 3 have a texture (the same), while object 1 has not (base color showing).

I'm dumbfounded.
Any help?

In order to see if the bug is on your Blender scene or either Yafray, you should render the first time using Blender internal renderer and keeping the same sequence as you described before.
