how can I split material on a packed instance geo in solaris 2025年4月16日22:50
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?

how to render motionblur for instance geo in karma 2025年4月13日3:46

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?
