This is my entry for Day 3 of HOULY! Today's theme was water - growing up just off of Jones Beach means it's hard for me to think about water without thinking about all the trash that floats around inside of it.
I decided to meet today's theme with a rig that would simulate the dynamics of some waterlogged plastic bits and bobs. This one is pretty simple - make a geo for the FLIP, convert it to a FLIP source with the shelf tool, add a geo for the trash, make it RBD, and then go and tweak FEEDBACK SCALE on the SOLVER tab of the VOLUME MOTION tab. I found “5.44” was a good setting for the FEEDBACK SCALE, some older forum posts made it seem like it wanted to be a huge number but that wasn't the case for me.
HIP attached, this is a fun rig!
