Material assignment to an instance

[cadjockey]

Hi all,

 

In an interior view I am working on I have created an instance of a pillow that sits on a sofa. This instance has used the assigned material of the original and in the viewport I can clearly see the material has been adopted.

 

However, when I render the view the pillow that was cloned as an instance does not render with the assigned material. It renders as a mottled dark brown.

 

What could be causing this?

show us an image of what you mean, it always helps... it could be that you have managed to duplicate it twice and now have coplanar faces????

The setting is in the material editor dailog box, under the drop down "options".

"Propagate materials to instance" with it ticked will apply materials to all instances and with it unticked just applies to the object selected.

 

Hope this helps

Hi James,

 

I have attached two images. One image shows my viewport which clearly shows the instance of the pillow (closest to the screen) which has adopted the material assignment no problem and the side table (to the left and part of the sofa (to the right) which show that they have been assigned the same material as the sofa you see in the centre.

 

The other image shows how the view renders. As you can see the pilloe is quite different to the other pillow even though it uses the same material and the side table look completely different.

 

What the??

tried deleting it and cloning it again?

 

but generally the blotchines is caused by lack of samples in the scene.

 

try increasing the light cache and irradiance values to get a better result.

I am not very familiar with MR, but I know these dark objects usually appear in VRay because of face conflicts. Check for duplicate objects in the problem areas and delete if found.

Are they mirrored objects? If so try a Reset Xform from the utilities panel on them.
