I asked a question, but no one answered it. I make models in ArtCam. And from it I get a depth map. Before buying Lightburn, I engraved this in ezcad, everything was fine. When I engraved this in Lightburn, artifacts appeared. They are not present either when engraving in ezcad or in the 3D model. I tried re-saving and so on. At first, I engraved this in grayscale, then tried to do it through a slicer. The result is the same.
This is a link to my post. There are photos there.
