I have noticed it for a while now , but this is time I need a bit of help to better understand whats going on here as its very important for the project. Corona displacement seems to be working really weidly. It seems to be disperssing out away from the point of view (camera) . Its not displacing in just one axis's if that makes sense. See attached images of my result and what it should be like. Is there something that I am doing wrong here or if anyone knows what the solutions is to eliminate this ?

Hello @usmangs
Please submit a ticket to us (including the problematic scene/material) - we will try to figure out what can be the cause of this behavior.

Just submitted one. Hopefully can resolve this issue .

This "issue" has been discussed many times in the forum. This behaviour is intentional, it is done so to prevent displaced mesh tearing at the sharp corners. To make this displacement skewing less apparent, you need to add more subdivisions to the source geometry, especially near the sharp corners. It's a similar concept to mesh smoothing - if you'll add turbosmooth modifier to a cube with no additional segments, then it will round that cube to almost a sphere, but if you'll add few additional segments, the cube more or less will retain its shape and the closer lines will be to the cube's edges, the more sharp it will be after turbosmooth. The same is true with Corona displacement, except it's not about smoothing, but about skewing. Hopefully you get what i wanted to say. In conclusion - this is not a bug, but a feature.
P.S. one of many past discussions about this on the forum: https://forum.corona-renderer.com/index.php?topic=38964.0

Just to jump in, even us C4D user's get this too. ;)
