Instanced Static Mesh Component does not have collision

I’m spawning instanced static mesh components along a spline to build a tank track but my instanced track tile meshes keep going through the floor. I’ve tried creating new instanced static mesh components and setting their collision to block all but they all go straight through the floor. Switching to static mesh components “solves” the problem but I really don’t want to suck up cycles using regular static meshes.

I’ve seen a few posts about collision not working on ISMCs but no definitive answer on whether this is a real bug or I’m just missing a step.

I can add the steps I’ve taken so far to try to resolve the problem if collision should work for ISMCs by version 4.16. I’d just like to know if doing so would be fruitful first.
