Sinfar is, by far, the best compilation. I think it has all of the beautiful head models. Just bear in mind many have broken shadows, and they use a different system in order to bypass the count limit. You need to sort through their haks meticulously in order to find them all.
Sinfar's extended heads have been converted to a helmet based system, and require custom palettes and scripting support for use now.
pasili is a little outdated, you could try anything from a social server like kissmet or sinfar head sets. the majority of their heads dont belong to them so its ok to use without there permission. if they do, that would be a violation of the original creators rights.
Ummm, yes, the majority of heads that are originally from other sources like the Vault, etc, are all fine, if you know what ones they are but...
How about the still sizable minority of heads that ARE created by Sinfar staff (many have been made that are exclusive to Sinfar), and DO belong to Sinfar's artists, shouldn't their creators have the same rights to decide permission of use as other artists do?
(Please note, not all Sinfar artists have given permission for their works to be used beyond Sinfar PW haks, esp regarding body parts, clothes and heads)
Would you say its ok to just take in-house content from standard PWs like Amia, Aerilith or Aenea without asking their content artist's permission first?
Should not social servers custom content artists deserve the same respect? Is offhandedly violating their intellectual rights really ok if it's not for others?
