you have to credit all authors of models icons and stuff used
no proper credits= go against rules = map rejected
i quote the rule:
Credit
In order to upload a resource, you must have some part in the creation of the resource. All other authors and sources must be properly cited
http://www.hiveworkshop.com/forums/faq/?s=&do=search&q=credit&match=all&titlesonly=0
not only in the description, inside the game too
and the stuff you put, you have to put it in the description not in an isolated post
I have a lot of imported models so I apologize if I can't find all the authors immediately and if you see your model and you do not have credit please let me know
better to find all, rules are rules,because if you miss an author, that author has the rigth to reclam, i really invite you to read the readme of any model, icon, stuff it will say: "please give proper credit" or something similar
my recomendation is to find all,make a list, and if there is something you dont find, delete it and use other stuff,
another thing, use the upadate tool, do not re-upload the map.
good luck
