I made this model in 3dsMax because I couldn't find any, and I needed a wagon for project.
This Model Imports very well into Vue'd sprit, and Poser, so should be compatible with most other rendering applications also.
Included in the Zip.
1.Buck.3ds - (This is the wagon)
2.Woodenpo.bmp - (Wood Texture)
3.Woodenpo(bump).bmp - (Bump Map)
To use this file, just extract all to a Handy location on your harddrive, and Import the 'Buck.3ds' into your choosen software.
