Well… the experiments with physics were… painful.
I spent much time, but didn’t understand how to expand animation (not duration of timeline) further far then 240 frames.
I spent more time searching for physical parameters in ‘physics’. No, they are in another window.
May be this could help anyone to find things that I didn’t find easily.
I strongly recommend the Instructors to remake this lecture and explain:
A.The rules of timeline and animation duration.
B, The speed parameter and may be gravity too (in Blender physics). The friction and bouncing are OK but not enough. Where the students can find them, by the way.
C. The rules of mass for models. For example in my scene spheres which are heavier than 20 kg fall through plains set passive.
Thank you
