Why does this happens?
I tried also to put the opacity map in the Refraction map (texture inverted and IOR set at 1) but same result. However if i render the single object (the original, let’s say) this issue does not occur. I also tried to disable the opacity map and didn’t gave no white result so it must be something with the opacity map.
