UE 5.6.1 Groom broken collisions

[papa335678]

After importing my groom, the collisions are completely wrong with strange floating disks. I’ve imported grooms in the past and not had these issues, so I’m not sure what’s wrong. All I did was import and check “Force Visible” under collision settings to show the collision shapes.

No settings seem to effect the collision at all, I’ve checked for floating vertices and other simple issues but it seems to be an issue on the engine’s side. Any ideas?

With “Force Visible”

Without “Force Visible”

Solved it, I was misunderstanding the “Strand Size” option under simulation settings, Strand Segments would a far better name for the option. Enable “Force Visible” to see what it’s doing more clearly. I had the setting too low, anything below 8 seems to break the collision generation system.

“Strand Size” above 4
