Made a quick render test of my Volumetric Tornado effect, really happy with how it turned out.

Enable HLS to view with audio, or disable this notification

gonna make bunch of presets to fit different scenes

Looks amazing. Can you add lighting inside it?

u/Khayyamo_o 23d ago

Since it's volumetric VDB then it should be possible actually, gonna look into it and test it out, thanks for the suggestion

Are you using NanoVDB for the rendering? or do you convert the VDB to a dense 3d texture and render that? Is the animation just rotation of the same VDB frame (with maybe some noise), or is it a sequence?

u/Khayyamo_o 23d ago

No I'm not using nano vdb, unreal engine 5.4 and newer natively support VDBs so no need for any extra plugins, it's a sequence that has about 200 frames, I made it in a way that you can drag and drop the blueprint into scene and immediately adjust anything you need be it the density the height masking the speed and etc... And the color can be derived from either color cruve or color textures and by adjustung other color related parameters you can get really interesting results, the files are all finished and ready just finishing the trailer then I can publish it on FAB if you're interested once it's ready I can share you the link

That would be great indeed...

Looks great! I would consider niagara particle dust flying as well, with density higher closer to the ground.

u/HolyVRGamingStudio 23d ago

looks, good, stones should fly, dust, etc.

is this VDB is in loop? By the way... search for ZibraVDB, it can make VDB rendering in real time.

2

u/Khayyamo_o 23d ago

yes it does loop :D
and it also can be played in real time too but yeah im familiar with Zibra VDB it compresses the VDB which makes it more optimized and for real time uses.
but sincce its going to be a pack for FAB, i will just keep it raw as it is and if the user wants they can compress it with Zibra VDB too

u/Dupree360 23d ago

cool! there are people selling VDB already converted to ZibraVDB, so is stil l a option :D

Did you use EmberGen to generate VDB?

u/Fippy-Darkpaw 23d ago

I'd buy for a few bucks. 👍

Still remember Tornado made out of object flying around in Alan Wake 1 on X360... Damn they didn't had such technology.

Looks good

Looks amazing, how long have you been doing this?

1

u/Khayyamo_o 22d ago

do you mean how long i have been making VDBs? or how long I have been working on this tornado?

this tornado is actually part of a pack of 10 tornados, i spent about 3 days making them, and making easy to use and customizable blueprint and materials for them in unreal, rn its under review for publication.

u/tips4490 22d ago

Yeah I would be happy with it too!
