Hi!

I want to use mask field of the Gas Surface Tension DOP to control surface tension with an attribute, but whatever I try seems to have no effect. I'm using the volumefromattr sop to create a vdb and try to source that in dops, but no luck. Any help would be greatly appreciated!

Cheers,

Felix

Anyone?

Hi,

Your setup is failing to import the mask field because you are trying to match to density field which is a non-existent field in standard FLIP. If you set this parameter to “surface” which is present in a standard FLIP sim, then it will import your mask field properly.

Thank you very much for your help. I'm still struggling to get this to work. I've set the “field to match” to surface in the volumesource. Although I really don't understand why, because by default when sourcing flip surface it's set to density. This whole dops/field thing is sooo confusing.
Another error (I suppose) was that I was sourcing my mask only on the first frame, I've set the activation to constant now. But still it's not behaving like I want it to, which is blending in the effect of surfacetension from one direction. Now the fluid is exploding in a weird way…
Any more help would be fantastic!
