I use Vue 7 Infinite. I have a scene where the terrain has an ecosystem. The atmosphere animation makes the long grass to wave in the wind.

The 1st 1000 frames (png) are done. In the next part an object comes in.

Is there a way to delete the 1st 999 frames and have the plants waving without
a jump from the new frame 2.

If I keep my first 1000 frames, when I ask a render from frame 1001 , Vue still does the calculation for the first 1000 frames and the  frame 1001 comes after 10 minutes. And I have a lot of testing, where to position the new object and to fix its trajectory, etc. So it a 10 minutes every times I want to render frame 1001.

If the background was a still picture that wouldn't be a problem.
What do you do for long scenes?

Long sequences of that magnitude are usually either for background, like through a window or viewport, or are considered a master shot....the 'single camera shoot the whole scene' that is broken up by cuts and closeups. But that method tends to be a holdover from celluloid. Most CG work is storyboarded and precut before any rendering is done, so that no more time is spent on a scene that needed. What exactly is the shot supposed to be?

  The first 1000 images (24/sec) is a spaceship that lands in a grassy plain.  Grass is waving from frame 0. The spacecraft cargo door opens ( frame 850-1000) and a flying robot comes out and goes to the planet inhabitant (the camera, you see through its eyes the whole scene). They are having a short chat and the robot got bat by the inhabitant (kind of caveman).

You could always set your render sequence to begin at frame 1000 instead of it beginning at the start.  Do you know how to do that?

Right click on your timeline and select "set animation start."  Then just dial in the frame number where you want your animation to begin.  The same works for "set animation end."

 Thanks Gary. But setting the animation start frame and end doesn't change anything. Just that I can tell Vue now to Render entire animation and it's going to start to render from my new starting frame.
The result (and waiting time) is exactly the same as telling it to render from frame x to y.

Vue still has to calculate the position of the whole ecosystem from the real beginning. (position of clouds & waving leaves)

And to be sure I just tried it.

One thing you could try is to keyframe the wind to 0 for the segment you've already rendered, and see if that speeds up getting to the segement you want to render.
I guess you'll want to check what (if any) continuity glitch this gives, if there is one you could try letting the wind start a little before the first frame of the rendered segment.

It's possible that a similar trick would work with the clouds.

How do I keyframe the wind? I thought that the setting in the atmosphere editor was for the whole scene.

AFAIK, if you change the wind settings at a non-zero time, you get asked if you want to animate the Atmosphere and then you'll see an Atmosphere row in the timeline.
