Blender-based matte painting plugin by Scenefiller.

this is the guide video, and the tool is 29 boxes. but a guess they are not following up well through the blender update.

the tool is quite rough but for your interest. 

they are based on nodes, quite similar to nuke.

the interface:

1. layers

2. matte paint

3. file management

4. color grade
