I haven't even made a working model-incorporated add-on, well, released one.
I will very soon, actually, very many of them (Not as large as some packs, but still quite big)
I would like to tell you, if it takes 5 months to get the script to work perfectly and seamlessly, I will do whatever it takes.
I'm tired of crappy add-ons with decent models, a model is only a quarter of the add-on.
I'll leave once I get tired of blockland, and by then, I should atleast have a slight degree of respect among the Add-ons section of the forums.
(All of the personally provided opinions about add-on quality, that is my opinion, and I am not forcing it, or anything else in this post on anybody)
