    Hey there!

    I really like it. It's very atmospheric.

    Only crits I have, is perhaps to add some stars. Even if it's only a few newly born stars. Also why not put in a nearby galaxy or a starfield in the background?

    Looks nice, and I am looking forward to your next image.

    ooh very nice, how did you achieve that wispy look instead of the generic "poofy" look?

    uhh..tweaking and tweaking.
    let see...hard to exactly narrow it down perhaps..
    its all hv sprites.. number of slices is 5.

    the texture has a stretch direction on z around 360 %.

    turbulence texture...with a slightly billow effect
    very low texture effect speed.

    The texture amplide i set to around 110

    the particle size must be big enough so it looks like they blend in eachother
    no small puffs here.

    The contrast in hypertexture is at a minus value at around 60.
    a gradient on the luminosity channel.
    a turbulence procedural texture in the dissolve channel.

    theres a colorful distant to object gradient in the color texture and
    above that layer is a turbulence procedural set to a difference mode that
    scatters the color out a little more randomly.

    theres three spline curves on two layers wich the hypervoxels sprites are applied to.


    thatīs most of the settings...
    did you use the volume mode for yours?

    hmm very interesting. Ya I used the volume sprite for mine, and then gradients in the color, luminosity, and density channels all using the "local density" input option.

    For the general shape of mine I either spray points or create a basic shape and sub-d it a bunch and then use the various tools to deform it's shame, then use the points2poly tool and apply the hypervoxels to that.

    What was your render time for that image?

    some more test with hv sprites on one or two nulls, render times ranging from something between 10-20 seconds in some different resolutions etc 500X900.

    should have made a better compilation or contact sheet with same sizes and scene name perphaps.
    I have some 150 scenefiles just with similar nebulas, so I have to try and be selective and save the best ones.

    Very Cool! Any chance of sharing some presets?

    My volumetric light nebulae presets are on my downloads page, so I practice what I preach!

    yeah..absolutly I will see what I can share, you are giving and sharing generously on your site so why not me.
    I have to figure out what to share thou, donīt know what kind of nebula looks the best so any feedback is good.

    Oh and as a tip, in most cases a painted background will do just fine for nebulas, but instead of starting to paint it all from scratch or using photos,
    we can set up some nice hypervoxels, render that out and even process and enhance in a painting program and then mapp it back on to geometry spheres cylinders or other in Lightwave.

    Wow, these are quite nice. For a moment I thought you were posting the reference pics you used.

    "Contact sheet?" You wouldn't happen to come from a photography background, would you?

    He..Thanks that was a nice compliment that it might look like reference images.

    no..those pics are actually photos from last night when I hi jacked the Nasa hubble teleskop and found som new nebulas..he..Kidding
    I still have a lot to improve on getting much better nebulas..some more time spending on it and some research also perhaps.

    I really wish there would be a new Dynamite release soon..some year?. having the demoversion was giving some promising nebulas with those smokestyle pillars shooting up like the eagle nebulae.

    yeah contact sheet..no I donīt have a real photographer background, I did work at two different photolabs a couple of years ago copying and all sorts of stuff, and some minor photo courses att school and media courses.

    hv sprites are fun and pretty fast, and with proper gradients and right amount of slices and a combination of several sprites a little more depht and volume can be achieved, it cant really be compared to volumetrics hv:s thou, but those arenīt very practical and enjoyable to tinker with due to rendertimes.

    Oki doki..but just one hv preset and just one textured environment background..I have to go through everything and sort it all up and naming stuff and so on..perhaps more presets later on.

    to get anything near my pics, thereīs a little more to it thou by blending different nebulas and so on, but this might give a little start.

    The size of these universal stuff is really ridiculous small ..he.
    so either models have to be adapted to this size or work around it.

    to use the textured environment, the dennis p plugin weather is needed and for stary background youll need ifw2 textures or create the stars by your own.
    I really love the weather procedural..this background wasnīt the best thou..but start by tweaking the scale on it and copy layers and add as additive and do some small small changes on that.

    Thanks!




    i should sleep...

    ran it through GigaPixel Ai, (lower image) thought i'd share,
    just cleaning up folders / files over here...
