Cool, thanks. Great to have the overlay!
Attached is a lazy version which utilises the particle system to create
a collision proxy.
Doesn't exactly make it faster but works and takes little time to set up.

Hey Frank,
Thanks man! Yeah, this'll be the convex hull thing - they can't model
concave shapes. Currently you have to split concave's up into roughly
convex parts and then, in the case of dynamics shapes, set them up as
compound so they stick together as one. If you switch on the solver
troubleshooting overlays you should see a rough approximation to the
physics world proxy shape. In the future there are avenues I can look
into with respect to making this convex decomposition happen
programmatically (although currently there's some hardcoded
assumptions about 1-1 Nuke geo object to physics shape which have to
be completely torn out to allow for this or fracture type bodies).
In the case where you're using Nuke shapes, then obviously its
slightly less easily to split up into sub sections, so instead I've
taken your cylinder and, from the point of view of the physics scene,
replaced it with a series of box collision shapes, forming the sides
of a cube (except the top). These are set to not render (so they just
offer a place for the sphere to drop into). The cylinder I've then
merged in after the solver node, so it appears in your render wrapped
around where the sphere lands.
Cheers
Jack

Indeed. I just had a quick play and it seems pretty awesome.
Attached is the script I just threw together to get my feet wet (just a
sphere bouncing off two cards and onto a cylinder).
I'm actually trying to get the sphere drop into the cylinder in the end. Is
this possible Jack? Currently it bounces off it when it shouldn't.
Awesome work man, I'm very impressed!!!
Cheers,
frank

Hey All,
Just to let you know I've popped a 2.0 build of J_Ops for Nuke 6.3 up
on Nukepedia, adding a rigid body physics toolkit for Nuke's 3D
system, as well as a range of tweaks, improvements and fixes to the
existing tools.
Check out the dev blog for more info: http://major-kong.blogspot.com/
Enjoy!
Jack
