Issue: Proximity Mines and Crash Pads Not Activating on Prop Floors

I’m using props as floors in my game (I know it’s unconventional, but bear with me). I’ve run into an issue where proximity mines and crash pads don’t activate on these prop floors. They just collide with the floor and turn off without triggering.

I thought converting the props into building prop blueprints might help, but it hasn’t worked so far. One suggestion was to place a thin barrier over the prop floor, but my floor consists of 1,000 destructible cubes, so that solution isn’t feasible.

I’ve tried adjusting the collision settings, but here’s what’s confusing: the same collision presets work perfectly on static meshes, just not on props. I also created my own cubes using modeling, and when I place the same cube as a static mesh, it works fine with crash pads.

Any suggestions on how to fix this? Is there something specific about props versus static meshes that I’m missing?

Hey Rustamovi4,

So you tried Collisions with Fort in the name like FortBuildingMeshPhysics ?

Some fortnite stuff works via the material, but I’m not too sure if it will work for this or not.

If you search for M Fortnite Base Parent in the Content Browser and make a material instance of it to use.
Theres a few options when you open it, adding textures, setting physics materials etc, but it also has Gameplay Parameters which includes the breaking effect when damaged.
