Very nice renderings. You may find some recently added features very useful for tour work.

Colorized Volume Rendering module in Sandbox extension can color a volume by a segmentation. You can use it to paint into a volume and display the result in 3D.

You can use Lights module in Sandbox extension to enable ambient shadows. It can make the rendering look much more realistic.

Improve ambient occlusion in volume rendering

@LucasGandel I’ve experimented with your code a bit and I think that IntensityScale property is not used optimally. If we use scaling < 1 values then the shadows are just become too weak - almost no shadowing occurs. However, using scaling > 1 values seem useful, as they can increase darkening. But we would not want to darken values that are below the VolumeOpacityThreshold, because that would just make the entire image dark. To solve this, I would propose to scale around the VolumeOpacityThresh…
