How to Enable & Render VDB Path Tracer in UE 5.3

- In this video, I will show you how to enable and render VDB Path Tracer in Unreal Engine 5.3, a powerful feature that allows you to create realistic volumetric effects such as smoke, fire, and fog. VDB Path Tracer is a new rendering mode that uses ray tracing to simulate the light scattering and absorption of volumetric data. You will learn how to setup VDB files, set up the lighting and materials, and adjust the render settings to achieve the best results. By the end of this video, you will be able to create stunning scenes with VDB Path Tracer in Unreal Engine 5.3.

Hi Winbush, I did everything Including from the material from your tutorials, but when I try to render using path tracer at mid-far distant, it became too pixelated like it's just a few voxels of vdb, however in Lumen, it's normal and good quality, I'm kinda stuck, can't find any solution, maybe you have some idea why? hope you can help, TIA
ayeee this looking REAL good! 🔥 I can see a bright future for clouds and game cinematics!
Absolutely 🤙🏾
You are a machine! The renders looks great.
Gotta stay busy during the strikes lol 😆
Awesome! Thank you so much for the video!
Absolutely, thanks for checking my content out🤙🏿🤙🏿
Can lie, Mr. Winbush always drops the best content ✌️
😁🤙🏿🤙🏿
Facts
@@COPISSTORM thanks fam 🤙🏿🤙🏿
thanks for sharing this. I would of never guessed to use the console command to view my VDB :)
Yea I'm hoping it won't be needed in 5.4 as they update this
Gold content as always :D
Thanks brother 🤙🏿
Amazing video thank you
Absolutely 🤙🏾
damn that looks legit!!!
Path Tracer is getting serious
Need a catch up on these vdbs they look amazing.
It's been getting really good lately
Thanks sir
You're welcome 🤙🏾
For stills you only need to increase spatial samples (remain 1 temporal) and for animations use 1 spatial sample with many temporal samples with reference motion blur turned on. You did the opposite, temporal would be better
Hi Winbush! I have a question regarding volumetric clouds. Do you know how to make them visible when rendering with path tracing?
Is there a way to have niagarra fluids working with path tracing?
Actually im not sure I've yet to jump into niagara
Great tutorial 🙏Have you run into the pixelated problem where the vdb becomes blocky/pixelated at certain distances?
Yea it depends on the vdb you use I guess and its density
@@JonathanWinbush Okay I appreciate the tip. Do you know if there are any fixes on this?
Very cool, thanks. Trying to get the free embergen cloud pack to look good but can’t seem to get the parameters right on the heterogeneous shader for color and absorption. Complicated 😮
I wish it was easier I've asked Epic to make an official shader to take out the guess work but more people should ask so it's high on their list
Has anyone had it where sometimes it works with PT and other times it just doesn't?
As an aside, the texture of the floor in the video is really cool, did you make it yourself and what should I do if I want to use this texture
Yes for sure is just a grid I use for checking UVs I can totally upload it tomorrow for you to download if you want
@@JonathanWinbush Thank you very much. Where can I get the download link

@@JonathanWinbush Thank you very much for your sharing. I will always follow and support you
Thank you master, May I ask about DeepEXR render with the path tracer are they possible without outsource RE ?
I'm not sure I fully understand the question
On regular render engines there is an option for DeepEXR files. Is it possible to render such a file from Unreal Engine as well?
@@JonathanWinbush
@@israelimc14 just regular exr from what I understand for now
@@JonathanWinbush Thank you, hope they will include it somewhere soon👑
@@israelimc14 yup make sure to post it in their forum so they can see all the request! 🤙🏾
what material are you using for the clouds? i can't get them to look that white
Just the basic vdb material setup from my previous tutorial
Oh, what should I do if after entering the command Vdb is still not visible? ue 5.3 has anyone encountered this problem?
does nanite displacement support in path tracer?
I've not tried yet
Just a note, I've had a lot of issues with enabled reference atmosphere under Path Trace settings while using the VDBs
I'll have to check it out thanks for the heads up
I can confirm this as well. If you have reference atmosphere ticked on, the path tracer grinds to a halt in the editor. It also crashes when rendering with MRQ. If the setting is ticked off, it renders the VDB’s just fine. It definitely wasn’t like this in 5.3 Preview. Hopefully they fix it soon! Thanks for all of your videos. They have been truly helpful on my UE journey!
Amzaing! How to use it in niagara?
I've not gotten into Niagara yet
Hi! I recently tried this again on 5.4 but it seem they removed many command including the one turning heterogenous volume on for path tracing did you find a way to use it yet? Thank you
I havent really touched it but I know they updated their docs with more current information on VDBs I'd check there
@@JonathanWinbush i see I will check it thank you!
Path Tracing dosn´t work anymore, in new versions. You have to modify the code of the project and then compile everything to have * Path tracing* option again. Epic changed this option , i dont know why.
I'm facing the same problem. I don't know why but it doesn't work anymore in 5.3
@@user-eg3mn2nq7y You have to get a new graphic card, if you have an old one it wont work. Another pay to win shit we gotta deal with. I tried to change the code of ue5 but didn't work.
Thank you for always being on top of everything new in UE Winbush!
However, I have a question. Seems like due to distance and the number of VDBs in a scene, path tracer seems to bug out and either start not showing some of them or placed cubes in the VDB itself. I have tried to set the .PathTracing.MaxRaymarchSteps to 1024 however it is still not resolving the issue.
Would you know what this stems from?
I think it's just a bug right now since it's in beta but on the roadmap its listed as there are improvements coming for 5.4
@@JonathanWinbush So after playing around with it a little, I noticed that the artifacts and the cubes are more prevalent when you are viewing the scene through a Camera Actor. I narrowed the issue down to the sensor size and the focal length of the Camera Actor.
It is very strange, but it seems like the bigger the sensor and the smaller the focal length, the less issues arise. I honestly do not have the knowledge to understand what is happening under the hood to cause this, but at least I've been able to narrow down the issue. Will definitely update if I find a permanent fix. Thank you for your reply man... you are pure awesomeness.
There is no option for path tracing, I only see lumen.
If you use the broadcast template it'll be auto activated if not you'll have to manually do it like so czcams.com/video/ZRLuaGuvrdw/video.htmlsi=otcN5ti0yo6biGvC
@@JonathanWinbush I think I found tbe problem. Im using a gtx 1080ti card. Apparantly UE dissabled the option for path tracing with gtx cards.
Oh yea ray tracing was only introduced with the 20 series cards but really you want a 30 or beyond
