Paint

Paints vertex colours straight onto the voxel surface. Paint, Texture, Smooth and Erase brushes. Density goes in one side and out the other untouched; only the colour channels change.

When to use it

Paints vertex colours straight onto the voxel surface. Paint, Texture, Smooth and Erase brushes. Density goes in one side and out the other untouched; only the colour channels change.

Hand painting is for variation you cannot describe as a rule. Anything rule-based belongs in Height Gradient, Hue Shift or Color Blend, because those follow the shape when it changes and strokes do not.

It needs the same Generate Settings node as everything else. Feed the upstream density and colour into Density and R/G/B/A. Strokes save with the graph.

Pins

InputsOutputs

Pin	Type	Description
`Density`	Number	The shape. This node never touches it.
`R`	Number	Red coming in. Leave it empty and the surface starts white.
`G`	Number	Green coming in. Leave it empty and the surface starts white.
`B`	Number	Blue coming in. Leave it empty and the surface starts white.
`A`	Number	Alpha coming in. Leave it empty and everything is opaque.
`Settings`	Voxel Settings	Wants a Generate Settings node: blocky or smooth, how fine the voxels are, how far to look for the surface. Share one settings node with Density to Mesh and what you paint on is exactly what you bake.

Pin	Type	Description
`Density`	Number	The shape, exactly as it came in.
`R`	Number	Red with your paint in it.
`G`	Number	Green with your paint in it.
`B`	Number	Blue with your paint in it.
`A`	Number	Alpha with your paint in it. The alpha of the brush colour lands here.

Settings

Setting	Type	Description
`Composition Mode`	Choice	How your paint meets the colour underneath. Replace swaps it out where you touched, Add tints on top, Multiply darkens.
`Current Brush`	Text	Which brush a click or a drag uses.
`Brush Rate`	Number	How many times a second the brush fires while you hold the button down. A single click always lands once. Size, strength and falloff come from the viewport Brush controls, same as mesh sculpting.
`Brush Color`	Colour	The colour the Paint brush lays down.
`Brush Texture Node Id`	Node picker	The image the Texture brush stamps. The list holds every Load Texture File node in this graph, so drop one in first and it shows up here.
`Texture World Size`	Number	How big the image is on the surface, in world units. Bigger stretches it further, so the pattern repeats less often.
`Texture Rotation`	Number	Spin the image on the surface, in degrees.
