RenderTexture to create a movie very fast

Questions & Answers
1

Hi All,

I am working on some functionality that will render a movie something in our scene. Basically we just want to spit out a series of images which will get saved to disk along with some audio and composited into a movie.

What we would like is for this to happen as fast as possible. We want to be showing something entirely different on the screen while the render occurs, and before we start we have all the animation values for all frames already defined.

What I wish I could do would be to launch my own thread which would just go frame by frame and apply the animation values to the screen, render a camera to a render texture, save the file somewhere and then do the next frame, while the main application continues running, but this doesn't seem possible.

Is there a recommended way to do this?

Thanks, Liron

This actually did not seem to be so hard in the end. Basically we just created a new scene and camera in a new layer which isn’t visible, and then frame by frame, rendered it to a RenderTexture, took the bytes and added them to a queue in another thread which writes it to disk.
