I’ve written a DSON (.duf,.dsf,etc) explorer-browser. It isn’t complete/optimized yet, but it does read/write DSON files and allows one to look at, modify, delete, and add entries into the files. This utility could be used to recover .DUF files that have become unusable in DS4 or Carrara.
Would anyone be interested in such a beast? Would it be worth $1 or $1.99?
I have prototype versions working for Linux, Intel Mac, and Windows.
Depending on the responses I may add object viewing (3D view), and the ability to make scene changes directly from the utility.
