Texture Face Order Parsing Changed?

[Maximillion Grant]

Has there been any word as to how and why the way SL determines the face order on upload has changed recently?  I upgraded to the newest version of Firestorm and had to reupload an existing mesh and the face order is not the same as it was.  I also tried the latest official SL viewer and got the same results on uploading the same mesh I had previously uploaded.  I'm not able to test the previous version of FS because it's blocked now so I don't know if it's a viewer issue or something on the SL backend that has changed.

Anyway the issue is that previously the face number was determined by the order in which the materials was listed in the DAE text file in the <triangles> area of the text.  I could alter the order by rearranging those sections between the <triangles></triangles> tags.  This was often necessary due to how my scripts worked when I needed certain textures on my mesh to have a certain face number.

This time when I uploaded the exact same mesh the face numbers are different and aren't affected by their order in the <triangles> section of the script.  Previously the order was (obvious) 0,1,2,3,4,5,6 and now the same faces are 4,3,2,0,1,5,6.   I tried rearraging the order as I had done previously but the new upload had the same faces assigned to the same face number so it seems like it's no longer determining the face order based on that section of the DAE file.

Anyone have an insight on this and how I can determine the order of my faces?

Materials are sorted alphabetically now.

Oh awesome, that's even easier then.

Thank you!
