Masking forces in dops

Hi,

I'm trying to get more art direction into some flip sims and I want to mask or blend off the effects of things like gravity, pop forces etc. I've managed to hook up mask field to a sop sdf to affect gravity, but things like pop wind won't work in that instance.

I tried a solver sop multiplying the popwind amplitude by the length of the velocity and again it does something but I've not found a way of visualizing exactly what that's doing.

Any suggestions as to how people localise forces or effects in dops, or visualise those things would be cool.

cheers,

A.

you can use vexpressions to mask them in any way you need, by sampling the volume of any geo based on Inputs tab from attrib or any other way imaginable that VEX allows

I personally like to have separate upstream POP Wrangle to create @mask attribute
and then use it in any vexpression of POP forces I want to use that mask for

like in POP wind you can then do:
airresist *= f@mask;

Hi Tomas,

I used a sop solver to group some points and set the mask attr, then under the pop wind used the multiply wrangle, works a treat. Much to experiment with still.
