Making your game moddable.

Gwenn:

Well, I’ve spent a week investigating modding support, and as far as I’m concerned, there currently isn’t any.

4.19 has an obvious breaking bug - it can’t build DLC. So modding is entirely impossible on that version, unless you fix a regression in the engine code yourself.

4.20 doesn’t have that bug, but despite dozens of hours of work, I’ve never been able to detect mod content from a mod pak, despite trying many different methods.

The asset registry works perfectly fine for the base pak, but won’t detect content loaded using OnMountPak().

The same issue happens if you let the engine load a mod pak from next to the default pak (which is not a practical method with Steamworks, anyway).

Loading assets manually with LoadSynchronous() won’t find mod assets.

I’ve confirmed that the basics of reading a pak file still work - I can dump the contents of my mod file and check that the assets are there. It all appears good and consistent. Actually making use of these, as of 4.20, appears impossible.

I’d love to be proven wrong, but I’d advise going with a different engine if modding is required.

I see you released the modding editor for Elium Rain, how you solved your problems?
