ShaderNodeLightDecay

Compute the decay of the light color using the distance between the surface and the light. This node must be used in a light shader.

Mode

Operator to use.

• Off : No decay
• Linear : Returns color / length (L). This is the slowest decay function.
• Quadratic : Returns color / pow (length (L), 2). This is a medium decay function. This also the physical decay.
• Cubic : Returns color / pow (length (L), 3). This is the fastest decay function.
