Record your sculpting and painting operations in separate layers for easier iteration during the creation process.
Both the sculpting and painting changes are recorded.

• Multiresolution sculpting
Go back and forth between multiple resolution of your mesh for a flexible workflow.

You can transfer vertex data such as color roughness metalness and small scaled detail in to textures.
You can also do the opposite transfering textures data into vertex data or layers.

• Primitive shape
Cylinder torus tube lathe and other primitives can be used to quickly start new shapes from scratch.
