Redwood no co collision?

I am currently trying to place the big redwood tree that people can fly/walk through. File: “RedWood_Dead_Log”, I have set the collision to “BlockAll, Ground, StructureFloor” and a few others. However, none of these actually cause collision with the tree. I can walk right through it (not the way i want to, literally through it.) What do i need to do so players can walk INSIDE of the tree without falling straight through the mesh?

Try opening the model. Then at the top goto collision, and from there try auto convex collison. It would auto generate some collision. May work for ya. (Tweak the settings when you click it)

I figured out what i was doing wrong. The dev kit has 3 different versions of the fallen tree. Two are able to be walked through, the third is not.
