jeffymphilip02 Posted May 23, 2017 Share Posted May 23, 2017 Heya folks, I've been trying to test out a setup where a volume inherits color from geometry which in turn is used to color smoke simulations. I have a attached a file with my setup - where I'm initializing a tempCd field and then transfering that to a Cd field with gas calculate and then advecting Cd with vel. However, the issue with the sim is the fact that it refuses to initialize multiple colors. I hope somebody can help me figure out how to troubleshoot this issue. Thank you! smoke_color_sim_test.hipnc Quote Link to comment Share on other sites More sharing options...
adrianr Posted May 23, 2017 Share Posted May 23, 2017 (edited) Without looking at your scene, have you double checked everywhere you're dealing with Cd that you are setting it as vector? Many things in Houdini default to float/scalar. Edited May 23, 2017 by adrianr Quote Link to comment Share on other sites More sharing options...

Many things in Houdini default to float/scalar. As far as my knowledge of dops go - yes. Unless, it is not sourcing in the right color. However I have set two colors and for some reason it only seems to source one over the grid. Quote Link to comment Share on other sites More sharing options...
adrianr Posted May 23, 2017 Share Posted May 23, 2017 http://www.tokeru.com/cgwiki/index.php?title=HoudiniDops#Volumes.2C_pyro.2C_colour Have a look through this file from Matt Estella and see what is missing from your set up. First off I'd suggest chucking down a volume vis sop to make sure your initial volume is being made correctly. Then work your way down from there.

The setup I was using is pretty similar to this. I had a placeholder tempCd field which was messing the sourcing up(somehow?). Quote Link to comment Share on other sites More sharing options...
