I work in the CG industry, and I have a small suggestion..i really don't know if is possible,but it would be great if xnview could support a preview of 3d files.Like small thumbs with the possibility to rotate the object.There are many application that do it.. i know, but i think that in "xnview way" would be amazing fast, and better.
I don't know anything about programming, so sorry if is not possible, i imagine that is a very complex thing to do.
By the way i've taken advantage to make this suggestion for finally register in the forum.
Thanks for your work,
bye
