[@kylemcneill5751]

For anyone wanting to use an animated VDB like an explosion or a campfire in the sequencer, you'll have to first drag the Heterogeneous Volume from your outline into your sequencer. After this, press the plus button or "Track" button and a drop down menu should appear. Under "compenents", select "HeterogeneousVolumeCompenent". From here, press the plus button again and under "Animation" in the drop down menu, add the "Frame" option. With this now added, you can key frame when you want your VDB's to start and finish their animation.

[@slumsnake1303]

Thank you very much for the tutorial! I would like to add that when importing VDB, all settings must be as indicated in the video, this is very important! By default, I did not have a glow control channel; as a result, the explosion resembled an ordinary cloud of smoke and did not glow at all, and there was no flame either.

[@JonathanWinbush]

Did you catch my later video by chance with the official epic games setup thats not manually put together like this?

[@franklinfisher8419]

This is a great video! Very in depth. Also, for anyone who may not know. For ease of access if you right click on an input node and promote to parameter it will automatically name the scalar parameter.

[@vazelevz]

Not long at all, huge thanks for this guide !

[@vladan.Poison]

wow. my head is still spinning !!! but the result is awesome.. i hope that the result is convincing when 2 or more VDB are in proximity. Thank you J.

Yea I'm hoping Epic makes an easier solution I was thinking it would be plug n play but of course not lol

[@privaatsak]

Thanks for the work in sourcing all this! For anyone concerned with the dark black shadows in the volumes for things like clouds, I found that plugging in a new colour parameter to control emissive color (multiplied by the Density) seemed like a good workaround for me.

Good stuff Winbush!

[@JonathanWinbush]

Thanks bro 🤙🏿

[@Fafhrd42]

This is really cool. I used the OpenVDB plug-in with UE 5.1 a while back to get some custom cloud formations for the Volumetric Clouds object out of a smoke sim I did in Blender, but this is definitely easier. I wonder how hard it'd be to use the velocity property of the vdb to build a flowmap instead of using an animated VDB. Also a couple tips: You can hold down 's' on the keyboard and click in the material graph to create a scalar parameter instead of right-clicking and searching (you can also hold down '1' and click to make a Float Constant and then right-click and select 'Convert to Scalar Parameter'). You can override the Sparse Volume Texture in the material instance instead of duplicating the base material and changing it there and making another material instance.

Hmmm, my material of all that just shows up as a big thick vdb box, like a box of pure fog, instead of any discernible shape. I've found that not all VDBs are equal - one I'm testing is out of Blender, but ones out of Embergen and Houdini all act completely different. Any tips on if I can't get anything coherent to show up? Kind of weird to troubleshoot did node exactly as you've got it laid out, its just my VDBs that are atypical.

[@AapoSomerpalo]

I had the same problem. Make sure when importing you have Smoke in the drop down menu of Attribute A > R. If you dont find smoke option there make sure you simulated it. In Max PhoenixFD you can check Grid Smoke in output. I hope this helps

[@matiasguisado3714]

Finally getting to test this but hit a wall. Around 2:00 you get the "Sparse Volume Texture Viewer", but it does't show up when I do the same search. Maybe I started off the wrong project type -Blank Video Production-?? Feeling like I'm missing something basic. Thanks in advance!

You can add a linear light or a rig of lights or do a 3 point lights. Copy paste the blueprint code for full control if you search on google ''Basic SVT Material in 5.3 preview (thanks to Thibault Lambert!)'' . Link the nodes to the material as shown in the video. Then play with the density, absorption and scattering parameters.

This is mind blowing, thank you so much for gathering this info together and working with the community. I can see this being great for static vdb,s especially for space nebula scenes. As for animated, it seems like the material flickers near the end, I wonder if it’s a frame rate issue. Maybe if unreal engines fps was locked to 24 or 30 would it not flicker anymore. Will it flicker if rendered in a level sequencer? What do you think?

[@JonathanWinbush]

I put this together quick so I didn't think to see what framerate the vdb was created in so that might make a difference as well. By default its set to 24fps in UE but I'm not sure what the actual vdb from embergen was created in. I'll def be doing more test
