Procedural vertex colors
Vertex colors are red, green, and blue values stored for each vertex in the model. Generators that create geometry can compute vertex colors if requested. Each generator has a set of "Vertex Color" properties that either set the color directly or modify a color they inherit from their parent. Modifying inherited colors provides a mechanism for smoothly transitioning colors across nodes and generators.
Note
Vertex colors are only computed when the "Vertex Colors" compute flag is enabled on the Tree generator.
You can also paint textures using procedural vertex colors in the Cutout Editor.
For information on painting vertex colors in Freehand Mode, refer to Paint Vertex Colors in Freehand Mode.
Viewing vertex colors
Render modes have been provided to see the vertex colors on the model. Select "Color," "Red," "Green," or "Blue" from the "Render" button on the toolbar to preview vertex colors as shown below.
Mesh assets
Mesh assets that are imported from ".FBX" files will retain vertex colors if they are present in the model. These colors can be added to or used to replace the procedurally-computed vertex colors.
Exporting vertex colors
To export vertex colors, refer to Games export options.
