If I work on a default void skin located in the airplane folder, do I have to specify something when I finish the template?
Basicly you can use up everything, if you Credit properly.
Internal or Skins on Requests, are from a Cooperation of Skinners or and Campaign Builders.
Depends. In past times there where Internal Templates available, alternatives
published. Some authors never published Templates. Dunno.
custom Default Skin in Plane folder (not published) } no Credit needed
Everything intended for Publication, yes, give Credits. If unsure ask,
90% can be tracked down.
if you refine a Template with parts of other Authors work, it's better
My experience was, always give or you end up like me,
getting stalked, mobbed by Prominent Skinners or their Fans.
They can ruin your career and have negative effects, which are hard to come by.
Can't recommend such mobbing, if you can avoid, bow to Community ethics.
If I don't have Credits, cause I can't find, I state,
unknown Author, if you know the author PM me and I'll add, Thanks...
It shows least respect (your intention not claiming) and you still care, even if not knowing.
Dunno what the others say
Best wishes to you
