Bulk remove collision prims from static meshes using Python

I imported a scene from a GLTF file. It contains about 1000 meshes of items and objects and lot of other details in the level. And then I find out that each of these meshes came with their own collision mesh baked in. In my case, the actual collision data that I will be using is in a separate mesh, so I don’t need the individual collisions from the original 1000.

Is there a way to remove all of those collisions? Re-importing the original GLTF file doesn’t seem to help, since there’s no options about the collisions in the import dialog.

Or maybe disable all collisions for all static meshes except for a few? I only have about 5 meshes that actually do need to have collision data, I can ignore the rest.

ps: it doesn’t have to be Python. I don’t care if it’s a plugin or something, I just need them deleted.

Well I found my own answer

static_mesh_path = "/Game/Imports"
asset_registry = unreal.AssetRegistryHelpers.get_asset_registry()
assets = asset_registry.get_assets_by_path(static_mesh_path, recursive=True)

for a in assets:
    if a.asset_class_path.asset_name == "StaticMesh":
        mesh = unreal.EditorAssetLibrary.find_asset_data(a.package_name).get_asset()
        unreal.EditorStaticMeshLibrary.remove_collisions(mesh)

But there’s a depreciation warning. It’s unclear to me how to use that new method, but this one works as of 5.2, so I’m sticking with it.
