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
Hello, after a small nightmare with switching to new whitewater system I'm a bit stuck with rendering an ocean shot: I would like to see a structure in water dissapear slowly into the abyss. Because Mantra is quite slow I don't want to use the volumes or a uniform volume shader for that (which is recommended). Absorption/Attenuation would be ok I think but it's missing from the Ocean Surface material! It's mentioned in the manual... What's going on? Any ideas how to switch it on? Screenshots, maybe I'm not looking at this correctly: Extra question - any ideas why Mist shelf tool was removed? We're supposed to build our onw on Pyro, right?
Hey all, I'm curious if there is a way to render volumes such as billowy smoke with absorption . Here is a reference of absorption done in krakatoa http://assets.digitaltutors.com/dtv_/bison_courses/558/detailed_images/5.jpg I've tried setting up a few lights and tweaking the billowy smoke material but I can't seem to get the right look as shown in the reference. Any advice would help. Thanks!
