In this video you'll learn how to perform Mesh Combination at Runtime in Unity! You'll see how I implemented it specifically in my free and open source minigolf microgame and learn the process for you to implement it in your own game!
Combining meshes has a load of benefits! From improved performance to reduced "ghost collisions", you'll learn the highlights and how to apply them to your own game!
