Thanks Gaia..
I have been to that page, spent hours reading the posts and trying to follow the video tutorials.
It was the best resource I could find, and I'm sure it represents a TON of work. I do not want to appear ungrateful.
@Codewarrior : I found many of the dozens of files you mentioned... I watched tutorials by all of the folks identifying which files might work best with which OLD version of Blender. One by one, I loaded the version of blender recommended by the tutorial, followed it, and my imports ALL resulted in wildly distorted meshes or non functional armatures. NONE of them (including the linked page), makes a reference to a Second life rigged preset export setting, or even operator presets. The closest thing to a mention of ANY export options requirements besides collada *.dae are bunches of references to correcting a z rotation. Even the newest videos cut to a 2.49 export add-in to "help".
I've been back to Gaias' site as well, and used the site search. The ONLY mention of Operator presets is as a "coming attraction", and the only mention of a specific "rigged SL mesh preset" appears in Primstar documentation as a "features available" graphic insert that is ambiguos as to whether it is a blender or PrimStar function. If you search for "Collada Blender" you MIGHT notice the graphic sidebar has a pulldown named "operator presets" , but again it is a graphic and not indexed....
So .. Gaia did finally "say the magic words" and I am flitting about in my new "me" happily. I only hope that more folks see the post here before they give up or waste all thier creative time trying to dig through the obsolete tutorials.
