So a project I author on one machine can give drastically different results on another machine. This problem can be especially disconcerting when working in mixed machine environments where people are working on the same projects.. List, I have no expertise here, other than to say that Motion is not alone in this regard. After Effects does the same thing if you have OpenGL previews turned on. The preview results vary depending on the card's capabilities. Final rendering is generally always software based so the rendered results are the same from machine to machine. However, you can render the final project using the graphics card if for some reason you prefer the OpenGL results. 3D is a tough area. Just look at all the high-end 3D gaming boxes - the same game can look dramatically different based on the graphics card in the host machine. While I don't like it, I do understand that any app that uses the GPU will also behave similarly. The thing that I really love about Motion over AE is the ability to change things while the animation is playing. From my understanding, this is possible because the GPU is doing all the work. Since the GPU can vary from machine to machine, the project results may vary as well. As Pete mentioned, what would be ideal would be a software based engine that could be invoked for the 'final' render that would produce consistent results, regardless of GPU. Rendering times would increase, but with the benefit of consistency. However, since I almost always now render my Motion projects in FCP right on the tiimeline, such a feature would probably need to be incorporated into the QT Motion engine to make it universally useful. That way if I create a Motion template for use directly in FCP, I can do so confident that no matter what Mac is used to render the template, the results will be the same. Ideally RT playback could be handled by the card, while renders would be software based. This email sent to site_archiver@lists.apple.com
