NO you didn't ripped those models. It's not the definition of ripping.
You converted them.
Ripping is when you extract a model or something from a game.
Is XNALara a game ?
You didn't ripped it.
Also... Saying "XNALara by [user]" isn't correct. XNALara, the program, was made by Dusan. The right way to say it is "Model originally converted and ported by [user]".
Just think it may be useful to some
noobs users to know how to credit their convertions like they should.
