I didn’t save this scene, so I created a new one. It has some artifacts as I reduced the file size, but it gives me the expected result when I render it with C4D renderer.
But I can’t achieve the same using Corona.
I’ve checked your scene any it’s probably not possible with corona at the moment. I’ll pass this to some more experienced 3d artist in our office to see if they can make this work.
The introduction of vector displacement support was a first step in full development, we appreciate the feedback on it.
