I make the mask image in blender by using the compositor workspace and adding this node setup: There may be better ways to do this but this was good enough in this case. I rendered out an image using Blender as well as an image suitable for a transparency mask which I will use later. I hope this help to make things clear and can get some workaround.For this mini project I started with a 3D sculpt for the frog using ZBrush and 3D coat.Īny 3D software you use is fine as long as you are happy with it and this is optional if you are not interested in the G’MIC stage, I’ll go into the hand drawing stage later in this article. I wanted to move the paint brush a little more further to the right of the object, because I wanted to only paint using those peaks and pointed part of the alpha.īut as I moved the brush tool to the right and the center cursor (yellow line) went out of the object, then the paint brush tool will be deactivated and I would not be able to paint anymore. First image is the brush tool is still inside the object so I can paint obviously. Here's a screenshot of what I'm trying to do. 3d coat always assume that when the tool's center cursor is out of the object, it means that you are not planning to use the tool anymore and would be just navigating the viewport (pan, zoom and rotate) so 3d coat will deactivate the tool and you will get a mouse pointer for viewport navigation. I mean, this is just probably how the brushes and the other tools in 3d coat are designed to behave. I'm starting to think that this behavior is hard coded in 3d coat. Ok, I just played around the conditions and also tried to use the stamp brush, but unfortunately the brush is still getting deactivated as soon as the center cursor went out the object.
