Maya version has Open/Close door (via setdrivenkey) and include all textures/materials READY TO RENDER as you see above
(check out the animation clip)
.ma (maya ascii)
.mb (maya binary)
Obj version is directly exported from Maya and you must separate poly that comes in 1 combined piece than apply materials and textures by yourself, so obj version is NOT ready to render.
NO POSTWORK ON THESE RENDERS (MENTAL RAY) , ONLY ASSEMBLED/RESIZED
