Time Drive SOP on VFXToolbox


I published an asset on the new VFXToolbox website: https://vfxtoolbox.com/
Its really easy to use and it has a nice way of showing demos using a 3D Viewer in the browser. I plan on uploading more stuff in the future.

Huge thanks to the creator, Guillaume.

Bullet Cloth

Recently, I have been experimenting alternative ways of doing cloth effects. I always had an idea about using the points as simple particles or spheres while using the edges as constraints.

I didn't know how to set up hard constraints until I came across this post on the odforce forums: http://forums.odforce.net/topic/24901-bullet-soft-bodie-in-houdini/

This is the answer I was looking for. Now all I had to do was use the sim to drive the geometry in SOPs. I am really surprised haw fast it is. What makes it great is that it uses simple spheres as packed primitives with Bullet Solver.

Here are some demos:


You can easily set up pin constraints by setting i@active to 0.


For tearing, you set a Primitive Group, called broken, to the constraints. The tricky part is applying it to the rest geometry in SOPs.


 You could get some interesting results with the constraint network.
