    Badum tish.

    clouds are light in real world, we are dealing with cg world now..right

    and for info, I had not that much of a trouble (except do not activate opengl preview) with the next highest dataset (480 294KB) with my..
    Asus desktop G20CB
    i7-6700 3,4GHz
    Ram 32Gb
    Nvidia Geforce GTX 1080

    the files contains these different resolutions of the cloud dataset so even though with lesser system may at least give it a go.

    wdas_cloud.vdb 2*861*156KB
    wdas_cloud_half.vdb 480*294KB
    wdas_cloud_quarter.vdb 66*764KB
    wdas_cloud_eighth.vdb 9*798KB
    wdas_cloud_hyperion_render.exr 4*433KB
    wdas_cloud_hyperion_render.png 1*976KB 1998x1080x16M png
    wdas_cloud_sixteenth.vdb 1*594KB
    wdas_cloud_mitsuba_scene.exr 128KB
    wdas_cloud_mitsuba_scene.png 51KB 333x180x16M png
    wdas_cloud_mitsuba_scene.xml 3KB
    README.txt 2KB

    As for hyperion render vs Lightwave render, the foremost noticable thing..I would say is the shadows, where in lightwave you tend to get sharp cut off for almost every shadow or darkness in that noise volume,
    Where hyperion seem to have a really nice algorithm to soften those areas out, just as they most often is portrayed in real life clouds as well.

    Terragen has a specific controll parameter for either soften cloud shadows or sharpen them for more detailed volumes, where lightwave has no such control as I am aware of, these kind of stuff is years of research for both Terragen and hyperion, with a Special focus and attention to deliver best looking clouds out there, with lotīs and lotīs of research of high light is scattered in real life cloud volumes and shadows etc...I doubt such research and focus..and resources for it to happen in reference to the new lightwave volumetrics.
    They could start at any time though

    Hi Guys, I made a video showing how I approached the DisneyAnimation Moana Island Dataset. Hope you guys enjoy.

    Just saw that, Oliver. I thought it was impressive. It made what seemed to be an impossible task, not only possible, but manageable. It was like entering a darken and spooky cave and you there, stepping ahead with a powerful lantern, showing the cave was not scary at all! ;-)

    ...that instance script seems more like a "Must have"

    Great video Oliver. LOL you even made a Disney json to LW instance converter on the fly!

    Great script Oliver.

    Now, back to the other topic (cloud): I did a test with the Disney wdas_cloud_half.vdb, too.

    I dont think that you can get the quality of the hyperion renderer with LW. It is very difficult and time consuming to recreate the hyperion render because we have not all informations. I did not find the the right view, sun position and background. And at least the wdas_cloud_half.vdb seems not be the same as in the hyperion render.

    not sure if the Krita example Prometheus posted was LightWave, if so...

    Hi Oliver.. great video! Thank you for sharing. Have you ever had requests to make a .PDB molecule reader for Layout with this technique? There's an old ball/stick pdb importer for Modeler.. however.. it's a one click, wait.. and it actually imports the data flipped on the Z I believe, which is wrong. Anyway.. .just wondering. Thanks so much!

    I have not, and considering that the modeler variation exists, I dont think its worth the effort either.

    Of course. Looked & didn't find it. Figured you were just too busy.

    Yes, I think you used my render there.
    Definitely looks better photoshoped, though I think I could have boosted the actua shading to get more white in there, and there may be drawbacks to resort to photoshoping it when animations is in the picture.

    The hyperion render is really something, terragen also seem capable of scattering light that way, vue I donīt think so, Lightwave...not seen any solution up til this point.

    Anyone who is up to reading and understanding, implementing the techniques, itīs a lot
    Hyperion volume renderer.
    https://graphics.pixar.com/library/P...ring/paper.pdf

    Notable is that we do not have any kind of nodal control of assymetry, not sure if anything could be improved there or if it would help with nodal trickery, it isnīt nodal I guess because the value change is all that may be needed.

    been fiddling a bit with absorption and various color settings, you can get some interesting effects there, not sure I can match that to the kind of soft darkness volume shading within a volume while still sending emitted light out to the rim edges within the volume.

    agree, not 100% there, so until NT rewrites the code, it might be of use.
    perhaps some can find some ideas/inspiration/clues from this PhotoShop file...

    it is basically
    -curves
    -blur
    -screen mode
    (used a mask here since i didn't have an alpha)

    very nice!

    did a PhotoShop test, tricky to get it 100% though.

    definitely going in the right direction, keep at it

    -------

    honestly i think a mix in between the 2 of you guys work would be the best, (imo)
    maybe the 2 of you should share info?
