Hi! I'm trying to upload a Unity WebGL build to https://sandbox.gamecore.com/upload
but I can't get it to run.
What I did:
Built the project in Unity (WebGL).
Zipped the WebGL build and uploaded it to Gamcore Sandbox.
After upload, the game doesn't load (blank page / stuck).
Questions:
What is the correct ZIP structure for Unity WebGL on Gamcore?
(Should the ZIP contain index.html, Build/, TemplateData/ at the root?)
Which Compression Format should I use in Unity Player Settings: Gzip, Brotli, or Disabled?
Do I need to enable Decompression Fallback?
Any required settings like Development Build off, Data Caching, or specific Unity version?
Are there file size limits or naming rules for the ZIP?
To make the build work on Gamcore, pack into the ZIP at the root level - index.html.
In Unity WebGL Player Settings set Compression Format = Disabled (don't use Gzip or Brotli, since the site can't handle them).
You can create the ZIP with built-in Windows tools, WinZip, or WinRAR.
Max archive size is 1 GB, and file names should avoid spaces/special characters.
I hope this helps. :)
