Paint Primvar Tool

The Paint PrimVar tool allows you to directly manipulate the values of primitive variables (PrimVars) associated with the vertices of a mesh. This tool provides a visual way to add artistic effects, control material properties, or create procedural variations.

To utilize the Paint PrimVar tool, begin by selecting the mesh you wish to modify. Once selected, click on the Paint PrimVar tool icon on the Shelf panel. Once the Paint Primvar tool is selected use the Tool Settings Panel to control its parameters.

Paint Primvar Tool Settings

Mode:

• Add: Adds the paint value to the existing PrimVar value.

• Set: Sets the PrimVar value to the paint value, overriding existing values.

• Smooth: Blends the paint value with existing PrimVar values.

Primvar:

• Select the specific PrimVar you want to paint on.

Value:

• Select a color or other value to paint with. This will depend on the type of the selected PrimVar.

Radius:

• Adjust the radius of the brush to control the area affected by each brush stroke.

Falloff:
