I concur with one exception. If we’re talking about a still image with or without a watermark or even a video, again branded or watermarked, in that case I think am over reacting. However, in my case it’s a .blend file, which gives them access to the mesh, vertices, edges, faces, etc., and according to their EULA they have too much control over my intellectual property. That’s the exception.
Perhaps I misread the course’s outline, and it did not ask me to upload a .blend file. Maybe a .obj would suffice, but even that makes me a bit uncomfortable.
However, I do appreciate your note. It was very thoughtful. 🙂
