Im trying to figure out how to do this for UE 5. Please subscribe and you’ll be the first to know when it drops.

On another note, if you're having trouble with shadows in this fork, make sure you change your DirectionalLight's useModulatedShadow parameter to false and set appropriate shadow distance. More info here:

This video being uploaded at this exact time has probably saved my project that I want to finally be rid of, so thank you.

[TheSitDownClown]

You are an absolute legend for showing us this. Thank You!

[pdubulous]

This looks like a great video. Super informative. I could not get past the HTML5.sh section no matter what I tried for hours.

YESSIR NEW YOUTUBE VIDEO LETS GO, it was really helpful thanks man - working on my own game

[和一木]

Is it normal that third-party plugins are not supported when packaged? Does the HTML packaging method not support any previously unmatched third-party plugins? I look forward to hearing from you

[GameZone]

when is the next football dev log curious to see the work you did :)

[Madve]

I had an issue with HTML5Setup script. It could not copy zlib.a file. However I had a space in the parent folder's name. Make sure you do not make the same mistake as I did. Do not have any space in the directory names. I use Windows 11 btw. Cheers

How does the UE program communicate bidirectionally with the front-end H5?
The webSocket plug-in cannot be used. Creating a WebSocket will cause H5 to report an error. Are there other ways to communicate?

[Ghuur]

Good stuff. Kept 4.23 for a Web project and can finally move it to 4.27. Did you manage to get it working in 5.03 at least?

[yashparanjpay]

Can i use this on 4.26? There is another plugin that is only compatible with 4.26.

[doggyminati-DGM]

not working for me after 13 hours of trying and it was very dangerous. I try this maybe with another pc but i never saw this crazy conflicts. This was a bad experience for me and i hope i never use python again makes no sense when you write a code and a other python version can not read the old code.

I needed a couple extra things for this to work. First, even when I got editor to load, had a bunch of errors pop up about dbgeng.dll . Had to rename this file: , I just put an underscore on it like so: dbghelp_.dll . That solved a mismatch version issue and now the editor loaded fine. The next problem was when I tried to package the html5 project. I was getting error about not finding "Windows" in the package log. Had to change line 83 of this file: to add a version folder to the hint path. On my c drive, the hint path xml object had to be: , instead of . after these changes I was able to successfully package a 4.27 project for HTML5 browser game.

We need something like that in unreal engine 5 not sure why they take it out

[tingxu]

I already linked my epic account to github. However, it show 404 when I clicked the link above. Is there a way to fix it?

[TrieuDuongLuu]

Do you make the package work in hosting server yet? I stuck at white screen with only 4 button like 29:37 too. My only way is put the package to Itch io

[markuslement]

I get this message
Setting up Unreal Engine 4 project files...
MSBUILD : error MSB1009: файл проекта не существует.
Ключ:

GenerateProjectFiles ERROR: UnrealBuildTool failed to compile.

Help me please...

[amanijeder]

Hi, everything worked well in editor. But after packaging to html5 it won't work on browser,
Uncough error.
Tried with empty project, worked well. How can I fix that, is that a blueprint not compatible with html5?

[YeXiuPH]

Hey but this means the User will have to download the files thru the browser right?

[doggyminati-DGM]
