the fluid sim is only capable of one domain per scene - and the domain is what turns into the actual fluid. so only one material, and therefore only one viscosity, etc. If someone has a workaround for this, that might help me out. I’m currently testing various different parameters of the fluid sim, but I’m not getting anything close at all to what I want.
I think I might have to go back to particles - but I’m having a hard time making them look like anything besides smoke. And it would be nice if I could get it to affect IOR like in the video above.
And the animation requires it to be more than a fake 2d animated texture, since the camera moves around the nozzle a fair amount.
