    I just released a new Blender extension for blurring images and scene backgrounds: extensions.blender.org/add-ons

    Under the hood, it uses the image processing libraries @pillow and .

    If you have ideas to build blender extensions yourself, join Brady Johnston and me at our talk “Extensions are Coming” at the Blender Conference next week, were we will be talking about how to develop Blender extensions. conference.blender.org/2025/pr
    (Recordings will be available as well.)

    #OpenEXR best practices
    - Real-Time Playback/Compositing: Use B44/B44A or DWA for faster I/O .
    - CGI/Rendered Content: ZIP (lossless) or PIZ (smaller files) .
    - Texture Maps: ZIP for fast access .
    - Layered EXRs: ZIPS for scanline efficiency .
    - Avoid Lossy Compression for non-color data (e.g., normals, depth). #exr #vfx #rendering #b3d #CGI

    Powiedziałbym, że dla #EasyCLA bardziej pasowałaby nazwa "skomplikowane i zepsute CLA".

    Po tym, jak w końcu udało mi się wysłać wniosek o CLA dla #OpenEXR, firma dalej go nie widziała. Spróbowałem jeszcze raz, i tym razem udało im się zaakceptować. Tyle że EasyCLA dalej twierdziło, że nie jest podpisane.

    Ale już po problemie, bo jakiś przypadkowy typ postanowił wziąć moją łatkę, wraz z oryginalnym opisem zmian, usunąć moje dane osobowe i wysłać ją, przy okazji zamykając moją — a autorzy od razu to przyjęli. Nie, żeby to robiło jakąś szczególną różnicę, bo łatka była trywialna (do tego stopnia, że ta cała bieganina wokół CLA nie miała żadnego sensu), ale i tak niefajnie, jak ktoś kradnie twoją pracę i usuwa autorstwo.

    I dare say a better name for #EasyCLA would be "convoluted and broken CLA".

    Even after I was finally able to submit the CLA for #OpenEXR, the company couldn't find it. After another attempt, they were finally able to approve it. Except that it still claimed I'm unapproved.

    However, that's not a problem anymore, because some random decided to take my patch, up to the commit message, wipe my authorship from it and submit it with a closing tag on my pull request — and upstream gladly merged that. I mean, it was a trivial patch (so trivial the whole CLA business was entirely pointless), so it's not like it matters, but it still feels wrong when people steal your work and remove authorship.

    I released v2.1.0 of my #research oriented #HighDynamicRange image viewer HDRView yesterday. Worked on lots of changes and improvements over the holiday break. Get the deets and binary downloads at the link below.

    HDRView v2.0 is out!

    Release notes and Mac and Windows binaries here: github.com/wkjarosz/hdrview/re

    Also runs on Linux (no binaries yet) and directly in your browser, even on iPhone/iPad! (just go to wkjarosz.github.io/hdrview/).

    Need to inspect an (#HDR / #OpenEXR) image on an iPad, iPhone, or a computer without a proper image viewer? HDRView’s latest beta seemingly now works in those cases. Just go to:

    wkjarosz.github.io/hdrview/

    And creating a home screen bookmark on iOS makes it almost feel like a real app.

    Does anybody use DWAA compressed exrs when rendering multi-part or multi-channel exrs? I converted some renders with AOVs using #Nuke and #OIIO and they got larger rather than smaller! Also, the compression ratio doesn’t have any effect on the resulting file size and visual quality of the AOVs at all.

    DWAA works with regular rgb channels though. Did I find a bug in basic #OpenEXR code?

    For those interested in , , and , there are some great fundamental open source projects you can get involved in...

    * OpenEXR
    * OpenVDB
    * Universal Scene Description (USD)
    * Open Shading Language (OSL)
    * OpenColorIO
    * OpenImageIO
    * OpenSubdiv
    * MaterialX

    ... just to name a few. And there's even more projects on the pipeline and DCC side of things, the field is huge and a lot of fun!
