How to get full detail texture for very large objects ?

Hello,

Thanks for the info.
Now I used this method to generate a detailed texture : result is 31 x 16Kx16K jpg files, total filesize nearly 1 GB.
I use autodesk FBX Review as a viewer, but this viewer can’t handle these big texture files.
Does anybody know a fast viewer application (Windows) for large obj files and textures ?
