Does anyone have any information about the XSI 3.0 format that was compatible with the Directx (6 I think) format in use about the same time period? Both were ASCII text based formats, or have some old X model files available so that I can study the file structure of the X format? Quite a few changes to both the XSI and X format have changed over the years making the newer versions incompatible older video games that used the now obsolete 3.0 XSI and X formats in the use at the time. Thanks, in advance for any feedack on my inqiry...BNG.
