RayTK

v0.42

A material that produces color for volumetric points relative to the input shape.

This is intended for use with pointMapRender. It isn’t useful for raymarchRender3d since that renderer only evaluates materials at points on the surface of the shape, and not inside/outside the shape.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Enable
Enable Fill	Whether to apply a color to points within the shape.	Runtime	Semi-Baked
Fill Color	The color used within the shape.	Runtime	Baked
Enable Edge	Whether to apply a color to points that are at/near the surface of the shape.	Runtime	Semi-Baked
Edge Color	The color applied to points at/near the surface.	Runtime	Baked
Edge Thickness	The thickness of the area inside/outside the surface where the Edge Color is applied.	Runtime	Baked
Blending	The distance over which to blend between the inside color and the edge color.	Runtime	Baked
Use Local Position	Whether to use the “local” position relative to the input shape when looking up colors using the Color Field input. If enabled, the coordinates used for the color field will be “before” any downstream transformations are applied. When disabled, the final global position where a point ends up in the render is used instead.	Baked	Baked
Use Surface Color		Runtime	Semi-Baked
Offset		Runtime	Baked
