Wonderful idea! I've signed up, and would like to offer a couple of suggestions for consideration:
1. There are dozes of Realflow tutorials around but none of them teach how to render the final sim. If you think about it, a perfect fluid sim is worthless if you don't know how to render it. Continuing that thought, I recommend that the MC include how to render any scenes or effects, rather than just build in C4D the scene or effect.
2. I recommend inclusion of C4D-to-post-production techniques. For example, for compositing does it matter whether to output object masks or material ID masks? Is there an advantage of one over the other, especially considering anti-aliasing? In other words, i'm suggesting inclusion of end-to-end production of scenes or animations.
I commend you on this initiative and look forward to being brought out of my darkness into your light.
best regards, David
