Static mesh foliage collision causing long load times

You wouldn’t be able to give a very quick step by step of what I need to do to get that working would you?

I have a map covered in “static mesh foliage” from a mixture of procedural foliage volumes and painted foliage.

The foliage has collision disabled but I would like to swap them for versions where the collision is enabled once they’re in close proximity.

To interact with my foliage I use box and sphere traces to HIT individual instances and send them custom data values to affect their materials.

It doesn’t have to be super detailed, just a quick step by step would be helpful if at all possible. The tools are quite expansive and there’s a lot to wrap my mind around even with all the documentation on the website.

Cheers
