Nice update Aaron
The heightfield preview should be extra useful for MEDEM.
The file format additions are always welcome.
The duplicate row is something that I've come across in my renderer's documentation (WCS). I don't think WCS native has the duplicate so it's renderer defaults to a format of no duplicated row. This can cause a gap of 1 pixel in heightfields in those formats that do have it I seem to remember...
I've yet to rerun my lighting tests that I was doing and I'm curious to try out the bump mapping so I'll post any 'findings'.
Thanks,
monks
