how to render random color on hair? i try many ways, i downloaded this project(viewtopic.php?f=30&t=68785),but i got the wrong result.

Try this — its a little bright, but just replace the gradient with something more preferable. For more realistic hair, use the Melanin and Pheomelanin inputs, described here: https://docs.otoy.com/cinema4d/HairMaterial.html

i have try you way to this but the result is not great.

i want the result like this. this picture not use the hair, but i want hair can make this result.

Remove the W Coordinate node from the setup then. That will force the hair to be the same color along the entire length.

it still dosent work.

Hi,
Random-Color node works with render-Instance objects, not Hair.
Try to replace it with a simple Octane Noise (Perlin).
The Hair are taking the color from the root.
