Ultra Volumetrics 

Thanks so much! What a lovely comment! I hope you like it and it'll prove useful in your projects. If you have any questions/issues don't hesitate to reach out. An awesome week to you as well! Thanks again!

Thank you!

Thanks appreciate it! Let me know if there is anything you'd like as I intend to have regular updates =)

I changed my mind. This asset has now been PERMANENTLY REMOVED from my wishlist!!! Haha, cheers. Will get back to you via email as a paid customer. 😃

Awesome! Hope you like it! If you have any questions or feature ideas let me know =)

Video tutorials will be finished either upcoming week or the week after that. After that you can decide if it's something you could use or not =) Thanks for your interest and kind words and good luck with your UE journey!

@vg Excellent & thank you, I'll look forward to it! I'm only a few weeks into binging tutorials, it may be a long journey, UE does everything =)

Thank you! I'd love to hear your ideas!

@@itsmebvg You know after more use It really does most if not all of the things I thought of to improve it. Turns out it doesn't need the "sea" height controls or the "sticky" function or even the 3dtexture & effect for mountain forests because it can do a form of all that.

@@DamienRamirez That's good to hear! I'm adding some cool new features in the next update which I had never even considered if it wasn't for others. Thank for your feedback!

Thank you! The shape is changed in a slightly less user friendly way. If you go to where normally the transform controls would be, slightly above it is the blueprint hierarchy and if you click on Fog you will be able to change the static mesh. Your idea with a dropdown is very nice, I quite like it! I'll see if I can incorporate that into the next update! The transform attributes are indeed hidden by design =) I like to keep things clean and almost always use the widgets to transform shapes in the viewport. However if you'd like to get it back it's quite simple to do so. Open the BP_UltraVolumetrics blueprint and in the top click Class Settings. Then on the right sidebar there is a Hide Categories section. Remove Transform from there, compile and save and you'll permanently have the Transform attributes back. The 4.27 and 5.1 versions are identical. Though in the upcoming update I will split those versions because I will have playable example maps and the input methods of 4.27 differ from the 5.1 enhanced input methods.

@@itsmebvg Awesome thanks for the quick reply! Ok cool, I'll go check that out. I didn't know you could hide the transforms - that's actually kinda handy to know. With regards to shapes, I take it any shape can work? Like you could model custom fog shapes maybe? Does shape scale matter or should the shape be a "primative" where you set box size or sphere radius directly. I have tested some quick volumes in my game test level and it looks great. Performance is great to (in packaged build especially). My only other thoughts are maybe some more fog noise types, if UE allows. I don't know if you are familiar with volumetrics in Houdini, but there are some amazing volume noises there (Voronois) etc. You can also get some cool results by distorting the world positions that the noises sample from. Anyways, thanks for the awesome blueprint.. can't wait to dig into it more!

@@michaelasquith4433 Any shape can work yes. There's 2 ways to go about it, either you have a shape that fits your desired area or you can of course just place 2, 3 or even 10 different smaller fog volumes and move them to the desired locations which in the end makes it look like one unified shape. Scale of the shape doesn't matter, the fog itself will not stretch as it gets its scale from the noise inside the material. I do have plans to create more fog noise types and will probably make a dropdown box for it. Thanks for the Houdini suggestion, I will check it out and see if I can learn something from it! Don't know if it will make it to the 1.3 update or 1.4 though. 1.3 is kind of a big update and i'm super excited about it, gonna add some pretty cool things!

It depends, it certainly can if you set it at the highest quality levels. However it also depends which platform you are developing for and what kind of gpu budget you have. Another factor is the amount of lights that are interacting with it and if they cast volumetric shadows for example. The answer can be complex and depend on a lot of different factors. A stylized top down game can be much more resource friendly than a 'photorealistic' style fps game. I'd say if your project can comfortably use normal volumetric fog you'll have no problems =)

Glad you like! Are you sure that there is an exponential height fog actor in your level with volumetric fog turned on? Take a look at the documentation to be sure you followed the correct steps.

Awesome hope you enjoy it!

谢谢

Can it enlarge its volume for application in a large city or natural mountain range? This effect was previously difficult to achieve in UE, and I am not sure if it can be achieved.

@@yantingye1677 It can, but that would mean you would have to set the view distance on volumetric fog to very high levels which is not recommended for performance reasons. At such distances it is much better to use 2d fog cards. With some fine tuning I suppose you could fade out the 2d fog card and fade in the volumetric fog at the right distances and hardly notice the transition.

@@itsmebvg Yes，you are right. I tested path tracing. Unfortunately, it is not supported. Although I know that path tracing in UE5.1 supports exponential height fog, after path tracing is enabled, your Ultra Volumetrics will not display but only exponential height fog.

@@yantingye1677 I'm afraid you are correct. After much testing it seems that although volumetric fog is supported, the material domain volume is not. Which is what Ultra Volumetrics is based on. I think it will be supported in the future. I tested both on UE5.1 and the 5.2 preview.

@bvg awesome. I may just need to dig into the documentation and testing but I'm not seeing it in path tracing, any quick tips or tricks I may be overlooking? I appreciate all of your work on making such a dynamic and necessary asset!

Hello, though I hadn't tested it myself I assumed since volumetric fog is supported with path tracing in 5.1, it seems the material domain volume is not. Sorry about that. Though I believe it will be supported in the future I can understand the inconvenience. Let me know if there is anything I can do =)

That sounds very familiar unfortunately 🥲 What were you searching for? Maybe I can improve some keywords or tags so it's easier to find =)

It works in 5.3, what problem are you having?
