Question

Height map artifacts when using clone stamp tool

Hi there.

I seem to be having a very annoying problem.

I am making a photogrammetry material tileable, I do this by adding a simple fill layer, this fill layer has a base color and height map and ontop a paint that is set to passthrough for both maps.

 

I then use the clone stamp tool. however, the clone stamp tool causes artifacts in the heightmap. bit depth is 16 and I tried changing it. I also tried changing the imported file type but nothing works.

This is what the artifacts look like, it might be subtle but it is quite visible when the light hits it.
Is there any way to fix this?

After a lot of testing, I discovered that this problem started happening on update 7.4.2 and above.

Before this, the problem did not exist, which makes me believe that this is a software bug.

Here you go:

When you use the clone brush on the paint layer under the fill you will see the effect. especially on hight map. move the light around to see it even better.

Bump.

 

I still have not found a solution.


So far I have tried the following to debug:

  1. Tried importing different resolutions
  2. tried importing different file types
  3. tried importing different bit depths
  4. tried a bunch more smaller stuff and looked around a lot for options.

 

If anyone can help them please do so as this is completely blocking my workflow and keeping me from making hundreds of photogrammetry materials as there is no proper replacement for painter using my workflow.
