I convert hundreds BSPs into a static mesh. It’s so complex that I can’t add collision manually. So how to add collision to a complex static mesh?Please help me.T~T

Open the static mesh editor and in the Details panel scroll down or search for Collision Complexity and set it to “Use Complex Collision As Simple”

The other option would be to use Auto Convex Collision and have the Convex Decomposition calculate the collision for you by opening the static mesh editor and from the Collision menu select Auto Convex Collision and adjust the settings to your liking and hit apply.
