Hello,

Can somebody help on setting the right shader for rendering smoke with Cd attribute ? I was trying on this shader but it gives error. Probably I am missing something. Would be great if someone can give a hint.

Thank you !

best regards

For the shader, try to use the imported Cd field to control the scatter, and a constant color to control the absorption.
