Okay, I'm going Insane here. I just got the 3dCoat free trial to learn stylized texture painting, but every single custom brush I make, creates black lines around the edges. I've have looked at similar forum posts with same problem Like this but nothing has fixed it for me yet. I know the problem is with Height information, which it for some god damn reason wants to put into the brush, but I just want ONLY the alpha information since i'm only painting color and nothing else.
My Alpha creation workflow is: Open new Photoshop file (1024x1024 or 512x512) and create the alpha using white color against black layer, when I'm happy with it, I delete the black layer and export it to some folder. Next In 3Dcoat I just simply create a new brush with the "open texture file" option and pick the Alpha I created. It should be this simple right? But no, it decides to create some height information which i do not need and are unable to delete.
I might be balding because of this issue and would love some help. Thanks in advance.
