ground, could I ask you to use Path.Combine (I think this one, but not 100% sure http://msdn.microsoft.com/en-us/library/fyy7a5kt(v=vs.110).aspx) instead of hard-coding \ as a directory separator? This would make running it on mono less awkward, not requiring to remember to set the MONO_IOMAP environment variable when running 3dsnus. Thank you for your time and hard work!
