I think it depends on the perspective of the person making the judgment. From a 3D Modeler's point of view, he'd think that if you didn't create the models, then it's not your own. From the illustrator's point of view, if you didn't draw it yourself (on paper), it's also not your own. I'm currently taking courses in 3D Animation and digital video and I'm amazed at how many of the instructors have never heard of Poser. I've even used the program in my Storyboards class because I can set up my scenes, camera angles, and characters and when I mention I used Poser for it they look at me like I have three heads. I know what you're speaking of when setting up the perfect scene with the posing, lighting, and camera angles, and finding the right props. Perhaps your colleague is still back in the days of the Etch-a-sketch and hasn't grown up to the age with more sophisticated software. By the way, I'm not knocking the canvas and paint either. Certain media is appropriate for certain audiences. This person sounds like a complete a-hole and maybe has a more narrow-minded perspective.
