Houdini Workshop for Beginners is a tutorial series that covers a wide range of topics relevant to people who are just coming to Houdini with little to no experience in the software. We take a project-based approach by building a couch scene that dabbles in many different areas of Houdini to get things started: From basic interface, to procedural modeling, basic cloth simulation, rendering, and building digital assets, this is a great way to explore the tip of the Houdini iceberg!

Have a feeling that this cloth brush is better than the blender’s version!

[@LoganPinney]

So impressed at how fast the cloth sims --- WOW! Thanks for the quick overview of vellum cloth brush.

[@MarkFancherFX]

Thanks! So glad you have been enjoying the videos!!

[@SwordOfFaith888]

Thank you this has incredible potential.

[@neptunediz]

Super cool!!!!))))

I never understand how vellum brush uses compiled openCL Kernals and gets super interactive while the vellum solver has to run a lot slower compared to that.

[@MarkFancherFX]

I think vellum also uses opencl, it just might be a low res enough sim that it feels like it performs pretty fast in a brush scenario.

Since ruffle and crease change the actual size of the polygon/triangle, doesn't that affect whatever UV we have coming from up-stream?

[@MarkFancherFX]

Definitely something to be aware of!

Is there a way to render an animation of the brush drag...?

[@MarkFancherFX]

Yeah! I am able to do it by inserting a file node right after the vellum brush node - on the file node, I set the file mode to "write", and give it a file path with $F in it ... something like C:/TEMP/cache/vellum.$F.bgeo.sc. then if i press play on the timeline and start using the brush it caches out the brush movements for me. If i hit stop on the timeline, then switch the file mode back to "read" it will play back the brush movements

[@MarkFancherFX]

This actually doesn't require unlocking the vellum brush node- so i modified my previous reply!

[@saebr]

@@MarkFancherFX thanks a lot, I truly appreciate it.
