@filipstamate i think people from maxon were trying to say is that in the future, scene nodes WILL have all the functionality xpresso has, and therefor chose to not put any more effort into xpresso. to me it makes sense, and i can totally see how scene nodes can make xpresso obsolete, but the question just is "how long will it take to get there?". and i'm saying that as someone who uses xpresso heavily on a daily basis.

Sebastian no longer works for Maxon. After an incredible 11 years he is now off on his own creating a very cool artist friendly version control system called Snowtrack. Worth checking out. https://snowtrack.io

As I haven't updated the documentation yet I have added 2 more demonstration videos to the first post: one showing the Export UV Canvas feature, and another to demonstrate the Bounding Box Transformation.

Previously I've dabbled with stepped pendulums, just affected by gravity, where the wire lengths increase in a linear manner - you can get nice sine wave type patterns eg here. I once saw a guy on TV - Stephen Fry - with a multi pendulum model doing just this, and he casually made a throwaway remark 'of course if you let it run long enough, the pendulums return to their original start positions' ie in a straight line. I thought 'that can't be true'. I tried (in C4D) all combinations of wire lengths and increments, but all I got was straight line start > sine waves > chaotic movement I once let a sim run for about 75,000F - but just got chaos and no alignment. Then I saw some math online that explained the align trick... I chose a time period for alignment - 20 sec Using the standard pendulum formula, I calculated the wire length to make the longest pendulum do 18 complete swings (period - T) in 20 secs I set the length of the next (shorter) pendulum to do 19T in 20 secs then the next pendulum to do 20T in 20 secs next 21T in 20 secs etc up to 27T in 20 sec for the 10th pendulum In theory, the pendulums should align every 20 sec. I set it running and the alignment was close, but not good enough. The problem was that the simple pendulum formula only works for small angles - it uses the approximation (in radians) of sin(x) = x which falls down over about 10 degrees. The math for large angles is quite complex - I decided to manually tweak my computed values until the weights lined up. So the final result was down to a mixture of python and intuition/guesswork. Works quite well. the pendulums line up every 20s - blink and you'll miss it

Will this training be sold through the Cafe? One under-served area in my mind is lighting and how to get great lighting using Redshift. Environments, IES lights, GI and mesh lights. When to mix and match local lights, HDRI, and GI? How to optimize your rendering times when using each type of light in Redshift. And most importantly, how to create a mood with the lighting. Another area would be composition (the rule of thirds, the golden rectangle, the golden spiral, etc) Lighting is only discussed relative to its technical aspects (eg. what each setting does). Composition never gets discussed - at all! This is a shame because there is a whole art to lighting and composition and so many looks that can be achieved with lighting for whatever mood you want to create. The art of lighting with Redshift could be a whole series in itself and a big winner because there is not much I can find on the "art" of that subject in the CG world. Dave P.S. You may also want to add a question on current C4D version number as well if you are looking for that information.
