I'm getting into painting textures onto my models using Blender's texture paint. I like that Blender provides the 'face selection masking' button that lets me mask out faces that I don't want to accidentally paint. However, when enabled this feature outlines all the selected faces with bold white lines - making it really difficult to see the results of my painting. Is there a way to hide this overlay?
As far as I know there is no such option, which disables the white lines. In Weight Paint Mode you have an option to display vertices instead of edges, but in Texture Paint Mode there is no option like this.
I think that using the Clipping Border Tool may be a good solution for you. Press ALT+B and drag a mouse to select the portion of the model which you want to be visible.
You can rotate selected portion, and paint on it precisely. And the most important is, there are no lines that may disturb you :).
Well, just download the latest Blender. Hiding the masked texture painting lines was one of its features:
