Hi,
what type of collision is the best for stairs (static mesh) that can be walked?
Wishes,
I would recommend you the third way to get a perfect collision for your stair: (4:55)
This Didn’t work out for me at all because my guy kind of floats when going up stairs that’s okay though
If you’re using Blender modeling software to design the stairs, I would recommend making a collision cage for the model itself while in Blender, and whenever you export the model, it should import the collision properly. However, I would use a bunch of cube collisions while editing the model in-engine, and just keep testing it, also try to play around with the settings of the collision and you should have some decent stairs 
I found a way to do it and it works. I will try to articulate it for everyone.
