Unless you have patented your items, you have absolutely no say in what I do with a finished build - up to, and including, taking that finished build to another grid. You may not apply a change in TOS retroactively, nor may you charge me for "extra licensing". The finished product belongs to me, and it's under MY control - NOT yours. You can NOT file a DMCA takedown over a finished build displaying your textures or sculpts, as long as they are not under U.S. Patent and they are used as originally intended - as a part of a finished product.
You can cry and scream all you want, but once you let go of those textures and sculpts, and I include them in a finished build, your rights come to an end.
If you wish to contest this assertion, you are more than welcome, but be prepared to cite legal examples. I already have. I don't want to hear your opinion or your point of view, I want to see and read the legal precedents you base your licensing ON. I don't want to hear a regurgitation of the same baseless drivel. It's facts or forget it.
