Here's my attempt at using rbd procedural.

It works much better. I load bgeo pts cache directly in tool, it takes 5-10s to load.
Forgive me for bad rbd sim:

Previously we done this with skeleton rbd bindings from Luca Scheller.

At some point I'll try this new rbd procedural on bigger scale. But for now it seems it doesn't have any problems with number of rbd pieces.

hey @Htogrom! I've been working on a destruction shot and I have a lot of sims with thousands of points. I'm fairly new to solaris and karma. I know this might be too much to ask but if possible, can you please send me a hip file or something like that explaining how to setup and render heavy rbd sims in solaris?

Here it is:

Have you figured out the correct workflow for RBD?

Hi,I have been troubled by a question for long time . When I import RBD packed fractures to Solaris , how can I split material between inside and outside faces?

Or I must unpack RBD fractures geo before import them to Solaris?

tamte
velocity MB is usually used instead of Deformation MB usually with geometry or point instances that change topology

you are importing packed primitives as native instances, each instance has Xform primitive so it can use Transformation MB with no issues

To render it however you need timesamples, which you can create using Motion Blur LOP or Cache LOP or writing it as a single .usd to disk

alternatively if you want to force velocity MB
you can choose Create Point Instancer for Packed Primitives on your SOP import
OR
you can use Houdini Procedural: RBD LOP

Thank you for your reply .After I check "Create Point Instancer" on SOP Import node MB works.

And May I ask one more question? When I import every fractures as one point just like this , How I can assign different material between inside faces and outside faces?
