Hi,
I managed to get collisions working using NSC material and Euler Implicit Projected (source code: stack.cc). However when I switch to the Runge Kutta 4 method, the collisions don't seem to work properly any more.

falling stack

Am I doing something wrong or is the NSC solver just incompatible with Runge Kutta integration?
