[TUT] Shattering Windows with Houdini's RBD Solver

In this tutorial I'll show you how to use the (relatively) new RBD SOP nodes to easily shatter a pane of glass and art-direct the shattering area. I will also cover a UV camera projection technique which allows you to render a final image with no need to do external compositing.
Special thanks to Bubble Pins for helping me figure out how to use these nodes. She's got an excellent series of tutorials on this which go into considerably more detail. Check it out here: / bubblepins
I am also using a very handy and free app called fspy to figure out what the camera focal length is. You can download it here:

I love your tutorials, you take time to explain every step and the mentality of why you selected the path you are explaining. You are doing something few others do, you are teaching not churning out videos for monetary gain and it shows.
I applaud your efforts and look forward to reach new learning session.

Aperture can sometimes be measured as a Diameter which allows light to go into the camera to hit the Sensor or Film Back.

You are one of tha best houdini tutorial channel in youtube ❤️❤️🔥🔥 love from india

[@RightBrainedTutorials]

Thank you!!!

[@mirkoventuri6660]

Nice one, never used those rbdsolvers. Btw, you can fix that Boolean "side faces" issue just by changing the settings in the Boolean node, and specify if the objects are solid or surfaces

[@danilodelucio]

Absolutely amazing man, you are so didactic! I really liked all techniques, thank you so much and please keep making more videos for us! ^^

[@Adenomamusic]

Thank you for the insights Case.

Hi Case, the 'meaning' behind the 41.4214 remains a big mystery. I had a long rant on Facebook about this, as it would make far more sense to have this 'Aperture' parameter default to '36'(mm) as then the 50mm focal length above would actually match 50mm on a full frame camera. Even SideFX themselves mention on their website that 36mm (or 24.89mm for Super35) would be the value to use :-D Thanks a lot for another great in-depth tutorial and I hope you're not as frazzled anymore now, after this nail-biter of an election is over ;-)

[@RightBrainedTutorials]

Yeah....another reason why Blender seems more thought out in some ways. I should ask some of my SideFX contacts why they decided on such an odd value. P.S. I want to say I'm less frazzled this week than last, but apparently the election drama is still going!

How would i calculate motion blur

[@gskeffects9607]

When I add RBD configure node After adding texture to the geometry everything goes wrong. Before rbd configure everything is fine but after rbd configure node textures disapear. Would you please help me?

Aw, you skipped the whole FSpy > Camera rotation part!

[@contentguy]

applying gravity causes my shape to fall again immediately. is there a way to pin it so gravity doesn't occur until brick hits?

[@midphase]

You can always keyframe gravity. Have it be 0 until you need the pieces to fall.

[@contentguy]

@@midphase good thinking. thanks.
