Vellum - updating wind per frame

Recommended Posts

Hi everyone,

Today I've got a simple setup for vellum:

I'm using a wrangle to drive wind with a ramp based of color. I'm able to get the wind to update per frame using the vellum DOP method, but i'm unable to achieve the same effect using the cleaner 'vellum solver' in SOP method. I was hoping someone had a solution to this, getting the same result from DOP to vellum solver in SOP.

The wrangle that you have in the sop version needs to be "first context geometry" instead of myself since you are updating the attrib every timestep. Also, make sure that you are using the same cloth constraint in both solvers.

Ah, I had played with the inputs and somehow missed to use first context - makes perfect sense. Thank you!
