Creating a time lapse effect using vray 1.5

[judderman]

Hi All,

I've done this before and found it fairly straightforward because it was a small scene. I rendered it brute force, no problem.

Have recently had to do a much more complex scene with far more lights, materials and such and am struggling to get the rendertimes down to an acceptable level. My question is regarding the best workflow for rendering a scene with a moving camera (pan to left) and a sun that sets with various lights coming on.

I'd always assumed that in this type of situation you'd only ever be able to render it brute force - is it possible that you could render out an irradiance map, per frame and use this to render your animation? Rendering it pure brute force is taking 4,5,6 hours per frame (at 1280x720) and this isn't something we can afford to be honest, we only have 10 machines and 4 of these are used during the day for work.

Anyone got any tips for rendering time lapse type animations with vray?

Regards,

Judderman

depends on how much time you have to render it and if the camera moves or not.
You can render it with GI turned off and have the sun moving, no Gi no flickers.

If the camera doesnt move you can render a still of the GI in the morning afternoon and evening and animate between on and the next in post.
In post animate the colour of the GI and the amount of GI.
