Hi, I'm trying to implement a PGS solver for collision response, but I'm currently stuck.How the problem manifests is for example a box resting on the ground, if the box is given a small rotation then it might spin out of control after a while.Also boxes in a stack are not stable but slide apart very quickly. (without PGS my box stacks are decently stable)Much grateful for any advice! int maxIterations = 10;for (int i = 0; i < maxIte
