In this section, we took an in-depth look at how to create more complex collisions. We also looked at how to create custom collision hulls in third-party art programs (such as 3ds Max and Maya). Moreover, we analyzed the Auto Convex Collision tool in the Static Mesh editor of Unreal Engine 4. We also discussed how the Max Hulls and Max Hull Verts parameters affect the collision that is generated around our asset. Lastly, we looked at all the necessary naming conventions required in our art applications that ensure proper exporting and importing of our meshes and collisions to Unreal Engine 4. Now that we have a very strong understanding of how to generate collisions in Unreal Engine 4 and third-party art applications, we can now talk about about the different collision interactions that exist in Unreal Engine 4 in detail.
