Anyone have a quick answer to why I can't get collisions to work with an object I made. I created a little wall with a cutout using a boolean. I have a glass plane that is fractured but it will not collided with the new object.

It will collide if it doesn't start inside the object however.

Is your geo has proper thickness to detect collision?
Visualize whether it's generating proper collision geo.

In the static object please check the collision geo representation. It seems like changing the collision representation from “convex hull” to “concave” should do the trick.

After looking at the collisions and all kinds of stuff for hours… you are correct it was literally only my thickness being too low…. thank you very very much haha. Time to make it thicker and just scale everything up a little.
