rbd problem with @active

[nghiatranduc94]

Hi, sorry for the noob question, i'm using i@active = 1 if @Cd > 0 to active packed geometry. but after a few frame when that point out of range(@Cd = 0), i@active back to 0 and the geometry stop moving, so how to make it stay active ?

use sop solver before dop to save active value

use group for select points by sphere and then in wrangler write this

i@active=0;
if(@group_active)
    i@active=1;

and put it to dops. Recreate dopnet and in rbdpackedobject use create active obj and check overwrite attribute and you get what you want
