[SOLVED] Upres Colored Smoke

[thomas67]

I'm not sure if I do it wrong or if this is a limitation of the Gas Upres.

I want to upres my colored smoke. Unfortionately it creates an extremly ugly thin film around my smoke.

My problem is very easy to reproduce, just use colored smoke shelve tool preset and then "Upres Container" shelve (don't forget ti add Cd and Alpha in advect_density1 inside Gas Upres node).

Is there a fix? Thanks !

I wouldn't expect the viewport to be 100% accurate, did you try a render?
also maybe have a look at this thread:

Hey bunker, 

yes it's also visible in render (actually even worse )

I followed your workflow, also used your trick with cdl, unfortionately it didn't solve the problem

[bunker]

maybe you could include a .hip file?

I guess there's no fix? =/

[bunker]

if you look inside the lowres smoke solver you'll see that Cd is handled separately, not just advecting Cd
so the fix is to copy those nodes inside your upres solver.
