Dops Collision Animation to Geo

[zinj]

Hello again!

 

Okay here's what I need to do. I created a VDB collision from a GEO OBJ import. I'm using this in the autodop to not only simply collide, but to float on the wave tank fluid as well. Okay this works!

I have a nice boat like wave motion.  I applied an initial velocity to the collision object, so it bobs with the waves up and down as it moves forward. Now, what I need to do, is transfer this animation back to the original base obj in the geo node. What would be the best way to do this?

 

Thanks!

I tried to write out the geometry in the geo node since it goes back and fourth from cops, but I only get the first frame when I do

a fluid render. If the cache is large enough, after the fluid render, I can hit play, and it'll write out the cache in the file node... but this doesn't work

when the sim gets heavy. I need a way to write out the animated geometry from dops (this is where i apply an initial velocity) somehow or use cops to apply the dop

animation to the original geo obj.

You can use dopimport sop to import dop data. wire it to geo which you want to transform with Import Style Transform Input Geometry.

You can write dop data at sop level using dopio sop.

Hope it make sense.
