Hi, i was working on a brick facade that needs some displacement to show the mortar gap and made my maps with substance, when i was rendering i found a nasty displacement bug with corona that is very obvious in the images below, i render the same geometry using Arnold and the result is way better and there is no deformation.
I tried with and without 2.5d
Im attaching the displacement map used on the tests https://we.tl/t-3IA961Ze05
Arnold version looks way better :(
If some one knows how can this work on corona it would be Great

It's weird, but the tif texture causes shading artifacts and even crashes 3ds Max for me as soon as I connect it to a material and/or do some adjustments. We will investigate...
I also saw it that you've submitted a support ticket about it and it's already being taken care of by one of my colleagues.

Hi Maru, thx for the response.
I didn't have any crash with the texture or scene, that's weird.
I was told (by your colleague) that there is not too much to be done here until there is some new progress on corona displacement tech.

As also suggested in your ticket the following can somewhat help with the current issue you are experiencing, until further improvements are introduced:
"...proceed and tessellate your geometry even more, and also apply a CoronaDisplacement mod modifier, this would help a lot with the face normal-expansion of your displacement. Lastly you might want to use min-max level values in your displacement modifier and try lowering your screen (px) quality to something like 0.5-0.8."
Lastly, do note that Arnold's displacement values scale differently, displacement intensity is somewhat low so you'll have to set corresponding values for corona accordingly. Arnold's displacement value of 1.0 is something like 0.1-0.3 cm for Corona depending on the scene setup. Example: https://corona-renderer.com/comparer/GZqyOW
