Efficient Preview Rendering in Blender


kernon-rendering-tipsKernon has posted a  a tutorial on efficient preview rendering at CG Cookie.

Preview rendering is an important part of your workflow and needs to be as efficient as possible. It's important to have strategies and techniques for the earlier stages of scene development that facilitate a smoother workflow. The less time you spend waiting for renders during the early phases of a project, the more time you'll have for fine-tuning and testing, resulting in better final results for your project. In this article, we'll take an overview of some of the different tools and techniques that are available in Blender to help you be more efficient with your preview rendering.

Efficient Preview Rendering in Blender



  1. Hark now and listen. This is one of those things that you think would be so obvious to animators, but is so often a problem for beginners.

    It's comparable to browsing on the internet with either broadband or dialup (well, maybe not that extreme). The more time that you sit waiting for a page to load is time lost that could have been used otherwise. Every little part lost isn't that much, but eventually it adds up.

  2. Maybe it's starting to sound old but :
    "You learn something new everyday"

    I only regret that the tutorial is not that much detailed about the Approximate AO.
    Like, is it in the current blender version? Is it a prototype?
    *Where do I click ?* T_T

    Otherwise nice one...

  3. PS : After re-reading it might appear as if I didn't know where the AAO is activated. I do.

    But it would have been nice to detail that in the tutorial in the same way other things have been detailed :)

    Like : "Approximate ambient occlusion can be activated in the Ambient Occlusion panel in the world buttons, by choosing the Approximate instead of the Raytrace gather method."

  4. Thanks for the write-up!

    I've added some more info for the AAO section. The AAO feature was one of the many benefits that came from the Big Buck Bunny project so, it's in the current version of Blender.

  5. It would be so nice to get real proper OpenGL preview rendering, especially for animations. With current Game Engine advances this can get pretty useful, but at the moment the OpengGL rendering doesn't really do a good job (for e.g. object centers, rigs. get drawn, world settings get ignored, no subdivisions, etc.). It would be nice to push the results closer to what the internal render does.

    Nice to play this "Border Render" ,it stills wait to a damm to render ,
    but at last only the part i want to check .

    Render Simplification not tested ,but to my pre configuration ,
    those features is what i want to see on the render test .
    High: Subsurf,Ambient Occlusion and Shadow Samples .

    What is a powerfull fast computer to fast render these full features and complex scenes,
    only for the thought when i imaginate waiting the render .....

    Oh and even if it looks amazing ,iam not that good .But its for what im giving a try .

    Thanks .

  7. thanks Kernon
    your tutorials are always really helpful
    and thanks for the themes too - the dark one is great ;)

    PS I tried to leave a message on your blog but it didnt work for me for some reason and there was no pic of the codeword to enter.. anyway I did say thanks here :D
