Hi there!

A couple months ago I did the Apllied Houdini Volumes 5 lesson and as part of that we're deforming a fog volume procedurally, as to create the look of a stylized tornado without having to run any simulations.
Now, I wanted to use that approach to do a logo animation as a fun exercise for a while and with the new volume deform SOP in H19 I finally tried it.
So far so good.

Now to my actual question:
Is there a way for me to create a vel-field from this procedural effect, so that I can then run an actual smokesim using those velocities?

Im attaching a .hip file that shows my idea and setup using a circle instead of the logo, bc Im unsure if Im allowed to just upload it anywhere I please.

Thanks!

Thanks for the help, that really saved me!

Hello there,

for the project I am currently working on, I have to destroy a wooden pavillon. The .abc file I exported from blender 2.93LTS seems fine until I convert it to polygons. I think there may be a problem with face orientation but I am not sure. When I then append an RBD Material Fracture, some some parts of the model have these weird artifacts, which I assume are the cutting geo used by the fracture node. (see screenshots)
Apparently the files are too big to attach to this post so I uploaded the needed files to wetransfer. The .zip contains a .hip file demonstrating the problem, a .blend file containing the model, the .abc I exported and also a .fbx version I exported.

Help would be very much appreciated, thanks in advance <3
