Thanks for the assets, it really looks good. But you should put a example scene with textured meshes with it, because now i just have a folder full of .obj files and i'm pretty lost, a unity scene example would be really cool !
I made these before I knew what I was doing regarding presentation. The stages were all created in AssetForge, rather than MAST back then. I may revisit these, create actual prefabs and demo scenes for Unity. I doubt I will texture them, however, not for a free pack. It's rather time consuming.
