You can do this using the pruning options on hairgen - either by bounding box or by percentage. These don't affect mantra rendering.

No problem - here's that rubbertoy scene.

I disabled some file caches to makes sure there are no external dependencies.

You should run the two File Cache SOPs in /obj/blob_geo/sim. These are for the FEM simulation and for generating the deforming collision VDB.

Hi!
In 16.5 your sim looks strange.No change of anything and start sim.Why is that?
Thanks.

Thanks Kai, these things really help a lot.

Thanks for the files, I also found the model used, just plugin the model and it all works

I do have a question if anyone mind sharing their wisdom. Super new to houdini and crawling my way through files to get up to speed.

There are a few attribute wrangle nodes within the geometry with the following lines in vex:

// attributes for modulating density masks
v@bbox = relbbox(0, @P);
f@x_axis_pos = v@bbox.x;
f@y_axis_pos = v@bbox.y;
f@z_axis_pos = v@bbox.z;

I understand that v = vector, @ = attribute, but struggling to understand exactly what this does and what the purpose is for this as well?

Thanks in advance
