Ok, so today Ive reserved some time to study how to tackle some problems with the more rigid assets of my scene. I'm trying to create some debries I can lay around the ruins of the old village that used to be there, near the tower... For that I am using the default convex shattering in ICE and placing objects around with the opensource version of the Momentum RBD solver for Softimage.
Here is how it is done:
First we build a pointcloud, the points position and orientation will be used to slice our objects. There is a compound for that, but as long as your points have a position and orientation, it doesnt matter much how you set them up.
We then apply "Create Shatter from Pointcloud". In order to set different materials for the ins and outs of the fractured object I apply a material for all faces whos angle is not divisible by 90. Hint: the modulo node returns whats left of a division operation.
I then set up the materials and a very simple RBD simulation with Momentum:
