Houdini cinematography study
A couple futuristic themed shots created in between work! I've put these disconnected shots together as a quick cinematography study. Also a nice opportunity to try Quadspinner Gaea for the first time. (Made in Houdini, rendered in Redshift)

Is it possible to animate the knitting ?
Really useful and helpful - many thanks!
Nice
This is BEAUTIFUL!!! Is there any chance you could do with different types of fabric? Thankyou for this. :)
Thanks!!!!
u so cool thank.
Great tutorial.
Hey Fabricio is there a way to keep the texture away from sliding over the geometry (instead of resting)? I allready tried a timeshift at Frame „n“ and transfer attribute on points, but it disnt work. The texture looks strange… any ideas. I appreciate your work.
Nicely done!
Thank you for this! Your explanation of dops and what everything inside is doing, is by far the best I have come across!
Amazing!🎉
Nice
👏🤜👏
That looks very great. It looks like it took a lot of effort
so clean buddy
Amazing work. But geometry brakes when trying to copy original geometry to sim. Any idea how to fix?
it looks so real in the viewport dang
Amazing tutorial 👏🏽
I have a toy which does something similar. It's from McDonald's and my aunt gave it to me when I was a toddler.
no way thats cgii whhhhaat
I seriously thought that this was stop motion. I only realized it was CGI when you showed the rig. Nice!
I LOVE this, super well done! Looks real :)
Awesome idea and you nailed it!
Hi, Thanks, it's fast. But Some crosses generated after sim. Is there a way to create perfect sim except add the sphere of vdbtosphere node(To Infinitely close to the surface of mesh)?
Thank you so much !
sooo freaking cool, thanks for making this man!! do you know how i would go about using the facial mocap data for daz character or any face?
Hi Fabricio! I really love your research works. Thank you for sharing! I had a question: Is there a way to transpose an animated spline directly to an audio waveform? Thanks!
Hi, thanks! You mean like a simple waveform visualizer? yes it is totally possible. This visualizer would be just a slice running along the full waveform as the audio is played. you can create a flat line in sop and use its point indices to query chanel samples from chops. There is a small conversion you need to do: time to chop samples (considering your channel sample rate), so your sop line middle point stays exactly the current time sample being played and first/last points corresponds to the waveform slice you want to display. But it is super easy overall, I have a hip example somewhere in my pc. Will try and make a tutorial for it soon!

Hi Fabricio can I do this tutorial with an object that has multiple UV Tiles ? Thank you so much though this was really intructive :)
no this would need a few tweaks to work in a multi tile case. Can't you just layout your current uvs to a single tile, just for the knit model, and optionally transfer back tiled uvs by proximity later?
Very nice!
These techniques are incredible thank you for sharing them!
This tutorial was so helpful for me. It's a subject I've been trying to understand better for a couple of years and your overview explanation of identity matrixes makes such a difference for me. You really should have more subscribers. Best of luck!
Thanks and I'm glad it was of some help. Matrices seem a lot more difficult than they really are (for basic transform operations), I felt much more capable when it all "clicked" and once I understood how these conversions between vectors/quaternions/matrices work.
This is such a nice tutorial. Thanks a lot Fabricio for taking the time to explain this really useful concept so clearly. Deserves more views!
Thank you so much for this Tutorial Fabricio, I learn't lots of new things! and not just about knitting! respect!
what a great video, in houdini 20 the sweep node is different, i saw suggestions to use copy to points instead but it does not allow the chain links to be oriented along the curve, they just keep their original orientation. Is there any way to work around this? Thanks!
Hi, yes use copy to points now! And right before the copy to points node add a "orient along curve" node to make the links follow the curve direction.
Yeah, and to rotate the chain link need apply Roll or Twist inside the Copy to Curves Node. If try to use transform node like in the video now can be problematic I think.
Thanks a bunch for the pointers! I ended up downloading the HDA and taking it apart to see how everything works, got everything working now and running chain sims for days!!
You can Select the old sweep in Houdini! Window Top Toolbar -> Assets -> Asset Definition Toolbar -> SELECT show always. then in the Sweep Node Parameter Tab you can change to the old Node.
Francis you just saved my ass. Thank you so much! @@Francis-yc9nc
Do you know how I'd go about using the infection as a driver for the rigid bodies simulation? A little confused on how to get that started
One way to do it is using packed geometry as bullet rbd pieces. Then you can set the "active" atribute of a piece to enable/disable it during the simulation. Since its just a regular point attribute, you can base the value off of the infection effect (via attribute transfer or whatever you like).
Show!
Do you know of any tutorials like this for maya? I'm trying to create a ski mask
nice tricks
Great Project ! Good Work
Excellent project!
Awesome dude!
it works! from the windows binary just crashes from the github version! great! superb Fabrico!
Hey, glad you have it working!! I'll double check the github version, but it seemed ok on my machine running Windows 10 with python 3.10.* Important note: MediaPipe does NOT support gpu inference on Windows! So the Linux version is far better in performance. =)
How did you get it working? I am facing the same problems as you had! :O
@@chillsoftyou're running the shipped binary or the python file directly from Github repo?
The shipped one I suppose. I have the github one as well though, but both behave the same way! @@fabricio_chamon
Hey could you please retry? I just pushed an update. Same links as before.
ill try again doing it this way via houdini
aww I got it working (VML_Streamer) but as soon as I put a hand or hands in on web cam it just crashes :( windows python 3.10.11
Wowsers gonna try this straight away
Irado!
Wow!
