I am still quite new to blender texture paint, and I have been following a tutorial on how to texture paint with layer. The problem I'm encountering here is every time I close and reopen my blender file the texture paint looks complete off(I have double check and save all image before closing).
An image before I close my blender(Apologies for the amateurish painting, I have been trying to solve and pinpoint the problem through retracing my steps)
Here, is the image after I close and reopen blender, as you can see the stroke end up with a "water-stained" outline.
I'm really confuse on what is causing the problem, or is this method which require the artist to finish everything in one go. An advise to fix this problem is greatly appreciated.
*Edited: Not sure if this is important information, but this is the setting that I using when creating the "layer" for image texture.
