And so have many other DAZ artists and VN game creators and nobody whines when someone uses their models without reference or credit to original lego combining modeller.
There is a huge difference between heavily modified models and minor tweaks.
Wildeer took a blank model that no doubt just came with the program and made it into his own, he doesn't need to credit the blank model.
Celtic took Wildeer's model and change it to the point you can barely recognise it's base model, he does not have to credit anyone, same with KisX.
Idylla however just made the breasts a bit smaller, you can't claim that it is your own creation when barely any work went into making it different especially when we have seen this thread other artists that done more heavier tweaks to the model then Idylla and yet credit Wildeer.
It's common courtesy to credit someone when that someone makes their assets freely available to people.
And it's even more grand considering Idylla in their timeline has complained that others are using their work without credit when Idylla doesn't feel the need to credit others.
