WebGL Compatibility for Unity-URP-Volumetric-Light

[librosang]

First, I would like to thank you for this amazing library! It has significantly enhanced my Unity projects on other platforms. However, I encountered issues when trying to use it in a WebGL build. The library does not seem to work as expected, and the rendered effects do not appear.

I would like to inquire if there is a way to adapt or modify the library for WebGL compatibility. If not currently supported, are there plans to add WebGL support in the future?

Hello,

I'm glad you found the package useful ;). However, I have no plans to add WebGL support.

I am currently working on my own videogame and barely have any time left to work on other stuff, and WebGL has never been one of my target platforms. Besides, I currently do not have much knowledge on the possible restrictions that make fog to not work on it, since it is a platform I've never used with Unity.

However, if someone wants to go ahead and try adding support for it, I could accept PRs :)

Let's port it ;) i'll try

Hello!

Thank you so much for replying and for creating such an awesome package! 😊
Good luck with your game—I’m sure it’ll turn out amazing!

And @francofuster, thank you for offering to help with WebGL support. 🙌

I’m currently working on a small game for a game jam, and it’d be great to have a WebGL demo version to share. Having volumetric fog in WebGL would really make the visuals pop! Looking forward to any progress on this. Best of luck to both of you!

sorry for using ai for replaying because my english is so so

Hello, just coming back before wrapping the year to share some info on WebGL support, as I reckon It'd be awesome to be able to use it on some jam games.

I have been a couple of days investigating it, and although I solved one of the issues, there are other issues with Forward+ rendering path freezing the browser on my side (both in 2022.3.55f1 and 6000.0.32f1), as well as realtime shadow sampling for "volumetric" shadows in Forward (and probably Deferred too, but have not tested it yet) freezing the browser aswell. This means that WebGL support is "on hold" until those issues are fixed by Unity.

I will try to post my findings on Unity forums and report the issues I found.
Meanwhile... Happy New Year !

For anyone really interested on WebGL, in the meantime, I went and tried out the new WebGPU support on Unity 6.1 (currently 6000.1.0a.9).

Good news is that it seems to work great. I made a couple of builds and the package seems to work fine.
Bad news is that it is still experimental on Unity, and support across browsers is somewhat limited yet.

Unity 6.1 with the WebGPU support should be released in April. Not that long from now.
