I was curious and noticed that for one - the mesh loads quicker in my custom file. Which is pretty good! I noticed there's a relative difference in file size as well. The 3D Heart model in obj file format is about 111 kb. Same 3D Heart in FBX Binary is 106 kb. The same heart in my custom mesh file is about 93 kb. Which, The 3D Heart contains about in total of normals, texture uv's, vertices and faces about 2,000 range.

Additionally, it's literally Indices free which just alot of easier to load. How is it indice free? It's already computed when it converts into the mesh file.

I've been looking into compression techniques and binary. However, it would literally have a higher compressed rate thought! So, I'll continue to keep everyone updated but this is one awesome adventure I'm on!
