Preferable Mesh Type for this Collision Model?

Hey everyone, I’m having trouble deciding which mesh type/shape I should use for a collision model I’m making for a Valve tree model. Due to the fact it’s a tree and the shape is a bit complex, I’m not sure how to do it properly. Using a simple cone works alright but I just can’t get it to fit the whole of the tree as the top point of it is a bit off a weird shape. I also tried seeing how other collision meshes for Valve tree models looked and they covered the whole of the tree quite well but I’m sure sure how I can do that. Anyways, I’m using Blender and here’s a screenshot of the model I want to create a collision mesh for:

Thanks in advance! :slight_smile:
