3DS Max to modelviewer

[Mine Turtle]

I have yet to get into 3DS Max, as I use Maya, but I will some time soon. My few questions are,

1) Have you tried sizing it down in Max? It looks huge.

2) What is the texture's filetype? (examples: .dds, .png, .jpg, etc)

1) Sizing it down didn't change the way my model looks in modelviewer
2) The filetype is .jpg

the texture needs to be a .dds filetype, and the texture size must be a multiple of 2 (256x256, 512x512 etc) (thanks to traggey for telling me this).
