Displacement map invert and have a bugs

[KiraGetto]

Hello everyone, I have a problem with displacement.

I created displacement map in ZBrush 32 bit exr. Often this map have a bugs in Corona render, but after a couple of minutes the bug may disappear just like that. Help me please.

Hi,
Can you tell how you import the map and what are displacement settings in your material? It is very important to import 32 bit displacement maps with gamma 1.0 and Corona material's displacement settings should be left at default: min - 0.0, max - 1.0

Yes, I did so. I solved this problem in CoronaDisplacementMod by putting the world (units). Not the screen (px). But maybe there is another solution to this problem.

This problem sometimes disappears, but if I remove tubosmooth and put it on again, the problem will return.

Are you using interactive rendering? If so, then displacement is not re-calculated in interactive rendering each time you move your camera (that would be too slow). If you refresh your rendering (i.e. stop and start again), then you should always see the correctly displaced mesh.

In your first screenshot looks like on your material settings Displacement > Water lvl. is activated can you please make sure that's not the case?

Can you please share a screenshot of your displacement map and your material Basic options?

I know, but this bug also happens in the normal render.

Can you help me? This bug everywhere. This bug is not in V-ray. But any map in the displacement section has this bug in corona render. This is in jpeg, and exr, and 16 bit, and 32 bit on any geometry. I reinstalled 3ds max and Corona Render. Install and past versions of 3ds max. No way helped.

Sorry for the late reply, and thanks for providing some image material. Can you please upload 1-2 scenes with which you experience the issue? (please include some of your displacement maps).

Use our private uploader and preferably use archive. https://corona-renderer.com/upload

This is how it looks with me:

What image loader are you using? Did you tried standard bitmap loader? Displacement work differently on standard loader and may fix your problem, i wrote about it but nobody answer if this is normal behavior.

Hmm strange, this is how it renders on my end from your scene, I did check most of your settings everything seems in order, I will try to recreate it somehow.

Can you please share with me what version of Corona you are using and what of 3ds max. Are you using any plugins to import the maps?

The strange thing is that the bug was only with new maps, and then it began to appear with everyone. I’ve been working in the corona for 5 years and everything was fine.

I use version 4 and 3ds max 2020. I experimented with older versions and it did not help.
I did not use any imports.

I did a lot of tests, took any displacement maps from zbrush, mudbox, and quixel. The only maps that work are standard 3ds max maps like checker or noise.

Can you please try and see how it's going to render with Corona v5 (also please try with latest 3ds max 2020.03 patch)?

You might have to do a complete uninstall of Corona and everything related to it the issue persists. Some quick questions, what's your OS and what CPU do you have?

In version 5, this bug is also there, but this bug is not with the new 2.5D displacement feature.

Hi,

Are you saying that this issue is not present with the 2.5d displacement?
