Roll Brush for Substance Painter

Paint with a rolling effect inside Substance Painter similar to the 'roll' modifier in Zbrush.

This tool is very much still at an experimental stage. Feel free to email me at supa_alex_liu@hotmail.com for any feedback and suggestions. :)

Requires Substance Painter 2019.2 or higher to work

Roll Brush v1.02 Release Notes:

- Added "Height Mid Value" and "Height Alpha Threshold" for adjusting height alpha generation.

Roll Brush v1.01 Release Notes:

- Fixed issue for Roll Brush where greyscale inputs such as Roughness and Metallic do not have their alphas respected when not using Mask Channel.
