How to use the RBD Procedural in Houdini 20.5

[@HoudinifxAlfredosanmartin]

Thank you, Tim. I’m very happy to see you again and that you’re better. Thanks for the tutorial. I’ve been following you for about five or six years now.

[@TimvanHelsdingen]

@@HoudinifxAlfredosanmartin Thanks Alfredo! that’s quite a while haha, almost as long as i’ve been doing Houdini tutorials (started doing those in 2016)

[@HoudinifxAlfredosanmartin]

@@TimvanHelsdingen I learned a lot of things in Houdini thanks to you since I started in 2016. At that time, I would look at the screen sideways and take notes in notebooks and folders, haha. I didn’t understand anything. I still do, but now it’s more dynamic, haha : )

[@TaekOhFX]

So happy to see you back!! Thank you for sharing your knowledge with us

[@angosalvo5734]

Glad you are doing better Tim and still kicking.

[@pragmaticvfx]

Nice method Tim, glad you are back!

[@philippwelsing9108]

Be well. Thanks so much for all you do for us.

[@williamhendrickson9581]

Great to see you back!

[@vipergx]

I was just earlier checking an older tutorial, wondering when are you going to post the next one and then I saw this in a Houdini group on Facebook. Nice timing. :)

[@zohahs5276]

Take it easy Van, hope you doing well. All the best wishes to you.

[@arsen_wasted]

First of all - be well, man! And now I'll watch next part of the video.

Thanks for the tutorial! Am i right, that if you use "file cache" points location in houdinirbdprocedural, you than get absolut path in usd.a file, instad of using "primitive location" to points, thet can be writen relativly? It make sense for farm rendering for instance.

[@novak_cg]

Did you figure out how to have deformation motion blur on the pieces? So far I have been only able to add velocity motion blur. Thank you for these tutorials!

[@TimvanHelsdingen]

the procedural picks up on the v and w attributes when deforming it so that's what it used, works out of the box if you enable it.

[@HDGamingVelocity]

Does this work with other fracture types as well? I guess the proc. Lop node just expected a point and geo cache?

[@TimvanHelsdingen]

@@HDGamingVelocity As long as it has matching names on the points/geo and the points have the correct attributes on them i think it should just work. What did you have in mind?..

[@HDGamingVelocity]

@@TimvanHelsdingen One is if the input geo is very heavy, rbd material fracture seems very slow. Two, if you wanted more art directability with voinore/boolean fractures

[@HDGamingVelocity]

Perhaps you are able to upload the house scene? Would like to see how you mix in the wood pillar in regards to name attributes etc

the funny thing about your talk about your wrist talk, to a set of people that will be the main takeaway, get wacom, get help before your arm falls off

[@TimvanHelsdingen]

@@isstuff Already switched to wacom and i made this video a year after I started seeing professionals to help with the recovery. It probably a chronic problem now but I can do most things again fortunately. I can work without any issues and I can do lifting as long as I keep my wrist straight. I can do gaming to some extent but just not too long. But yeah everyone should be careful to not get the same problems I did, don’t wish this upon anyone

[@TaekOhFX]

This is by far the most confusing node name I've seen in Houdini. Why Houdini in Houdini node name? and also procedural has too broad meaning. The only thing related is probably RBD then RBD what..? haha

[@TimvanHelsdingen]

@@TaekOhFX They essentially call everything that can be rendered directly by HUSK(the command line USD render thingy) a procedural and i don’t think they even require Houdini/engine licence to run. They have multiple of them, there’s also the hair procedural and the ocean procedural.

[@TaekOhFX]

@@TimvanHelsdingen Interesting that it also comes with ocean and others! It makes more sense now

[@novak_cg]

@@TimvanHelsdingen They have two types of procedurals right now. Basic - usually called Houdini something, that does not require any Houdini license run (not even a hython/hengine) and the User procedurals/All - user can create their own procedural (we have created RBD Procedural in H20 previous to this) but it requires atleast Houdini Engine license to run before starting the render to process the input before rendering the image.
