    EmberGen to Eevee Update VDB Rendering

    https://twitter.com/Yokohara_h/statu...90479032426497



    a tiny bit of info from the developer once embergen is more or less complete he will be focusing
    on a realtime fluid solver tool with the same level of workflow based on fast access
    gpu algorithims used on embergen. granular solver also coming soon to embergen.

    Embergen looks really cool and Eevee is awesome!

    Still waiting for mesh collision support in Embergen, don't care if its just primitives, its needed.

    latest feature updates:

    All new node graph based system which allows you to easily create fluid simulations.
    This node based system allows for things like multiple emitters, multiple force types,
    noise injection, masks, shared parameters etc.

    - Emission from meshes.
    - Collision with meshes and primitives.
    - Looping simulations via blending flipbook/image sequence frames.
    - New camera system which allows you to place multiple cameras and animate them.
    - New atmospheric background rendering.
    - Simulation and rendering performance optimizations.
    - UI Icons to improve your experience when using the software.
    - Tabbing between parameters in the UI.
    - Simulation upresing/upscaling. This isn't a post process effect, so it will allow you to upres volumes before you export them.
    - Hundreds of other small changes.

    Major features still on our list to implement for the initial beta version.
    - Color gradient mapping.
    - New timeline editor.
    - Tab system to clean up the UI.
    - Progress bars for saving large sequences.
    - Texture packing for exports.
    - open vdb nodes export with emissions

    There's no mention of any of this on their website, is this available to people who purchased the software now? If that's so, count me in.

    Very cool. Now I know they mean business.

    LW users will only find fewer and fewer "nice/useful LW third-party developments" unless and until Newtek/VizRT get their act together and resume strong third-party developer support. Specifically, they need to provide comprehensive, updated programmatic API access to ALL features / config / state (read as: "bring SDKs' access feature-current"), provide holistic example code esp. for those new APIs, and update reference documentation as well.

    Pleasant surprise would be nice, but not worth holding my breath.

    If you have Octane installed in Lightwave it works perfectly with vdb exports from Embergen not sure about native open vdb import will have to test that

    Anyone want to try in LW2X19 a 200 frame vdb export from embergen at 1GB exported in about 1 minute

    a simple one here

    Yes, it works...though the simulation is offset from origin, so you have to zoom out a bit in layout and find the sim a bit below the null used for vdb, and you ofcourse also have to rotate -90 in pitch for it to be right on the coordinates.
    Also to small resolution in order to get decent quality, and as always..hard to get full thickness with scattering channels without it going pixelated.

    As for the sim, not very exciting...and not much you can not do with standard blender fluids I would say..except for perhaps those small little curl convections in the beginning of the flame, which is best seen in the top image.
    Just some slight changes in gradients of the emission and scattering channels, all is treated within those texture channels and nothing in the nodes.

    Nice test Prometheus - you should try playing the bigger file vdb for a higher quality.

    How is the render times by the way ...

    Where was the bigger file? (EDIT..oh..found it.)
    As for render times, donīt know, just tested with vpr only..then actually deleted the files since I thought they werenīt much of a of use for me.

    Well yes, the higher res did obviously provide a better quality without the artifacts.


    Rendertime for still in 1280x720, 5 camera samples..no adaptive sample, GI 10 rays, 16 indirect samples, 5 minutes 9 seconds, on my asus G20 Rog, but then I was having a lot of firefox tabs open, and blender, and gimp, andkrita, and LMMS with a lot of vst plugins going.
    100mm step size

    System...

    But anyway, octane would deliver faster renders, the rest is about tweaking the scatter and emission texture gradient layers.

    I need to install the blender 2.83 volume branch, to check the VDB import and cycles render in there to compare.

    As for eevee, donīt like the volumetrics for fluid stuff that much, itīs cool for volumetric ligthing, but can not compare to cycles rendering.
