Color channel of the Redshift material volume node issue...Hi guys, I would like to use the color channel of the Redshift's material volume node. 1) I created a vector point attribute called "absorption". 2) I added this attribute's name to the "Volume Rasterize Attribute", attributes list, to create a volume called "absorption" 3) In the "volume source" node of my pyro DOP, I added "absorption" as the source and target field (as vector type). 4) I add a "VDB vector merge" node before my pyro material node. 5) In the RS Volume material, I add "absorption name into the color channel. But it doesn't work..! How can I fix it? Thanks for helping. Absorption_01.hip
