If you are making a movie that is an hour long you will find it best to create your projects as individual "scenes". That is to say, each project is a complete scene and ends as the scene finishes (it will be very unlikely you will have a single scene that is longer than 15 minutes). This will make editing easy and is the way movies have always been made. You certainly don't want projects ending in the middle of conversations, or in the middle of action scenes etc. which will only make life difficult for yourself.
I have 100 objects, which moves independently in my first scene. At the end of state they have some position,rotation, e.t.c. I need continue (start next scene ) with exactly this placement of objects. (i.e. this is chess party, and placement of figures). It's main point.
I found a solution
1. Go to last frame
2. Place transform key for every my 100 objects. (100 times)
3. Delete all frames except first and last.
4. Move last keyframe to first.
5. Extend scene, and save it under Part2.iproject
It's quite annoying, so that is why i use "SCENE SNAPSHOT" term (frame with ALL keyframes of all parameters).
Maybe somebody develop this script with python support?
Or we have more simple solution?
