Hi I'm currently following the vellum docs for using the collisionignore and collisiongroup string attributes. Everyrthing works fine when I specify the collisionignore group directly, however when I try to tell vellum to ignore all groups except for one that I specify, it doesn't work. I've made a basic scene to demonstrate the problem. Here is the code that I use: s@collisionignore = "top"; - This one works s@collisionignore = "* ^bot"; - this one doesn't work TLDR “* ^foo” rule stated in vellum docs doesn't work fo me, what am I doing wrong?

hey guys, is there a way to make the Pop Collision Ignore node work with the grain solver? I really need to avoid the collision of one granular solid object, it works fine with normal particles but not with the grain solver. grains_avoid.collision_1.01.hiplc
