Field Colour Ramp Material
Updated: 13 Aug 2025
Uses a colour ramp to colour a field system based on density or temperature. The field will fade through the colours in the ramp as the density/temperature get higher or lower.
Field Colour Ramp Material
Method #
The field colour ramp material is suitable for colouring the field system based on attributes such as density or temperature. If you input a Colour Ramp to the temperature or density colour ramp input, the field will take its current density/temperature value and assign a colour based on the Colour Ramp. Lower values will pick colours from the left side of the ramp and higher ones from the right side. You can control how values are picked along the ramp by using the Temperature Curve Power property.
Parameters
These properties control the core behaviours of the node.
Parameter Details Tint Colour Tints the field.
Density Density of the field.
Scattering The ratio of scattering vs absorption.
Scattering Colour Controls the ratio of scattering vs absorption per colour channel.
Density Colour Ramp Blend Control the amount that the density colour ramp affects the field system.
Temperature Emissiveness Control how emissive the colour generated by the temperature colour ramp is.
Temperature Curve Power Control the shape of the curve which the colours will be selected from along the colour ramp
Modulate Temperature Colour By Density Should density affect the brightness of the temperature colour.
