Rendering an animation. Need tip

Recommended Posts

I'm rendering a 1200 frame animation, so I'm trying to find the best rendering settings for a shorter render time. Not so obvious. I find the Physical renderer gives me better results, but not by much (compared to the Standard renderer). I get my best results by enabling GI, but this more than doubles the render time. Are there settings that can help me get similar results without long render times?

How did you optimize your scene? As far as I know, that plays the role when rendering with Standard or Physical, but I might be wrong. I didnt use them in a long time. Also altering Anti Aliasing or resolution can also help you. If you are using Global Illumination, Samples are also something you can adjust and optimize to suits your scene. There are many things you can do I guess, but really depends on the scene and how much you can optimize.

  • What do you mean by "optimizing my scene"? I used the default GI setting, Samples set to medium.

    By reducing number of polygons, light sorces etc.

  • Can't really reduce number of polygones without compromising the quality of the image.

    It is possible to entirely replicate the look of GI with standard lights, but it takes a lot time and experience to set this up. You use can use bounce lights, shadow casters, negative lights etc to produce very good lighting that renders much faster than GI.

     

    Have a search about the web for 'direct illumination' and you should find some explainer videos for that approach. Not sure how many are free though - it is quite a lengthy subject to light a whole demo scene...

     

    But if you haven't got the time or experience to do that kind of setup, the price you pay is in render time, so it is well worth taking the time to optimize your scene to keep this down to a minimum... this mainly involves tweaking render and GI settings so you get the maximum quality for minimum render time. But I have absolutely no idea what is in your scene, so can't advise what you should change.

    Hi,

     

    Optimizing scene and render settings takes time and knowledge to understand it.

    I was long time user of Standard and Physical render engine, they are very capable for producing near photo-realistic render images and animations, but issue has always been long render times, especially when using GI in animations. Simply, it's slow.

    My advice is, if you can, try Redshift, it's GPU render engine, one of fastest render engines, producing production ready photo-realistic results, both stills and animations.

    If you must use Standard/Physical for some reason, attach your scene here, and I can take a look and give some advice.
