Its saying its trying to load Fuel and Density from your sim (ie. 0xA), but its only able to load Fuel (0x2). Any ideas why Density isn’t available in that stream?
In order to create the DensityGradient channel you need to populate the Smoke voxels, so there isn’t any way to change that. I can however, make the error message less stupid!
You can still use the PRT FumeFX object without Smoke, you just can’t enable “Seed in Smoke” or attempt to use “Density” or “DensityGradient” via a KCM.
