It took me some quite a lot of time to understand it. Most people told that models are only for Tennogen usage, but also said that models can be edited in other softwares like blender, maya, 3dsmax and so on. I understood that it is allowed only to make skins and warframes, but I didn't find anywhere it is not allowed to use for other purposes. Can someone explain what the hell is a yes and no-no restrictions?
