I know this is a couple weeks old, but I thought I would post here what I had posted in another thread reguarding a working exporter for 3ds max 6.
Here's the info:
The direct link for the export plugin is here:
(Download the bin file)
If that doesn't work you can go the long way:
Click on "dotXSI xchange for Max - Export" , then click on "dotXSI4max" (the name seemed a little deceiving to me, more like it was for max 4 and not 6 ). You'll want to download the "bin" file.
Hope that helps anybody that hadn't yet found a working one. I know it was hard because I had a hard time finding this one.
I know it works because I've tried it and graves also found success with it here:
Like I said in the quote, I think it might have been easily overlooked because the name has the number "4" in it when it really means the word "for" and it makes no mention of 3ds max 6.
Yes, the JO skeleton will work. You'll just need to remove some bones that aren't used by JA. You can find the information reguarding that here:
