I was looking at some real-world dolly/crane/steady camera rigs and I've got inspired to develop my own 3D solution about it. Please tag animations/jobs/productions/wtv »rp_CameraRig« or post a comment with the link Ok? Would be lovely to see what you guys have been doing with it :) This rig is free for personal use, if a studio/company wants to use it please contact me. Let me know if you find it useful and feel free to drop me suggestions/comments/ideas or anything.

Create and bind nulls or point lights to object/curve/pointcloud points. Support normal/particle orientation. Just copy compounds to corresponding project folder, select object in scene and run one of the scripts. If »Instance« ICE Tree will be placed above simulation or modelling stack you can get a nulls or lights that will stick to object points. Rename standard »Null« and »Light« names on scene, as well as »ICETree« name in object stack, script uses them for own purposes. SI 2012 required.

A muscle primitive, that works on ICE. Based on Shekn article (Russian). It support squash/stretch and spring motion. Copy compounds to corresponding project folder, import »aMuscle« model to the scene. Y scale of curves is responsible for size of a muscle in the control area, X scale change thickness of geometry. To view options of model select the »Show Custom DisplayInfo Parameters« checkbox in Visibility Options of your scene. If you want activate or deactivate spring motion, select model null and run »CreateSpring« or »RemoveSpring« script. I've not see the way to envelope muscles yet, so you can try it by yourself, there is example scene that you can use for tests. SI 2012 required.

Per request in this si-community thread, user Matic posted this wave ripple effect using an ICE verlet/spring simulation as a quicker alternative to other water simulations.

Yeah the problem is that these ripple compounds (like one I did a while back and a few others have made) they tend to use a spring-based approach which isn't a true simulation of water per se, but rather a simple spring network with some force propagation thrown in... you can get good results, but if you are looking for some of the fine details of behavior you would get in real life you need to go to a much more complex simulation. And right now for softimage that would mean maelstrom (proprietary) or a sph-like solver like lagoa. Realflow/realwave might be a good solution if you are willing to go outside softimage.

But if the spring-based solvers are close, you might be able to do some cheats and get them to do what you need. Here's the one I built... It's about as simple an approach as I could make, I slammed it together in a couple of hours to meet a sudden need in green lantern (we were developing the look for the scene where a woman gets whisked away by a flood of green-energy »water.«) So no promises on whether it will help or not, but it's at least simple enough you can hack at it. I hope it helps a bit.

Video usage instructions available here. From Simon's site:

I made this script when I discovered a decent way to clean a curve so that I could make a bike chain in ICE. There is an operator called 'reparametrize' but that doesn't do the job fully. Also I have attached my ICE Compound to distribute points along a curve but that's not entirely what this is about in case that has problems :)
Note: For CLOSED curves this seems to be working very well, OPEN curves are more trouble but I added something in so the script will close it for you and you have to do some manual work after. All is explained in the video above!
