My collision groups editor panel is bugged. I didn’t do anything with it to change it. Last thing I’ve done that maybe affected it is I updated Roblox studio since I haven’t used it in a while. It doesn’t allow me to edit or view the relationships between the groups, I can only make new ones.
unless there’s been a UI update, the UI for the editor should look like this (A screenshot I found on ByteBlox’s youtube channel, the video where it comes from is from late 2023). Still it should at least give me an option to edit and correctly view the relationships between the groups.
Bumping this as I am also experiencing it. As I go down the list of collisions in the editor, I lose the option to check the box for collisions on other groups.
