This foot model comes in three separate resolutions:

Resolution 1: 1248 Polygons
Resolution 2: 4992 Polygons
Resolution 3: 19,968 Polygons

This product also includes:
One High Quality Color Texture (2048 x 2048)
One High Quality Normal Map for Each Resolution (2048 x 2048)
One Cavity Map for additional texture creation (2048 x 2048)

The main file format is in 3ds Max 2009 *.max format. However, this download also includes *.3ds, *.dxf, *.fbx and a separate *.zip containing all of the texture files.

*Note - The third resolution does not come in *.dxf format because it exceeds the maximum *.dxf polygon count.

Thank you.
