Vray - Animation - Analysing scene / frame change - If no change; duplicate previous frame instead of rendering new.

[AshtonWoolley]

Hello,

Not sure if this suggestion would work but it's an idea I would like to explore.

When rendering animations, there is sometimes a point at which everything stops for timing reasons and there are no changes in the scene of lights, materials, animation. Lets say, for 60 frames. Would there be a way, instead of rendering those individual frames, vray analyzes the scene to see if there is any change in scene and instead of rendering a full frame it simply duplicates the last frame rendered with a new frame number # while everything is static, until it detects a change in the scene and then conducts a full frame render?

The only issue I can think of now would be for noise patterns looking static.

Seems like for animations with long pauses it could dramatically reduce render time.

Let me know if my thinking of logic is incorrect.

Thank you

With storyboarding this shouldn't be an issue. Duplication is of course massively quicker in post and allows for extensions/reductions as is needed.
As an example, I'll plan animations in Max completely, for sure, as that gives a great idea of what I'm after and accords to any storyboard, though I'd rarely think of rendering camera pauses, unless there was
an object flying into frame or something similar. Even then there are of course other ways of rendering just that object in order to shave render times.

Grain can be matched/added in post if necessary, to mask anything static that is unsightly, so you're covered there too

Maybe others will disagree...
