Good day to everyone, I don’t quite understand why this strange effect occurs, drawing with a brush, one texture to another. I tried to set the channel to 60% gray, all textures were downloaded in 8 bit. I will attach a link to the project on Yandex.Disk, you can go to download 2.87 GB.
Here’s a video of the strange effect: Texture flicker effect - YouTube
There are no layers of mesh durgs on top of each other, what gives this strange effect I don’t understand?
