Clay render bug?

Hi

so first bug I've noticed is when I activate clay render, and set it's material... it renders fine all with that material and all... but in one of 5 test renders I did,,, material that was added in the clay material somehow applied on the scene without returning the original materials... btw I canceled the rendering in half of it's progress when that happened.

so that's it for now

Cheers

Vjeko


edit: I canceled that render when lighcache was calculating
