I've created a resource pack add-on using the fusion mod, and it uses a custom directory to prevent it from being loaded when fusion isn't installed. But because global packs doesn't detect an assets or data folder, it doesn't load the resource pack. A new config option that allows modpack makers to add custom directories to this exception would be a good solution. So for people using fusion modpacks without an assets or data folder, they could just add fusion-overrides to the list, this would also make it compatible with other mods that add custom directories.

Not a major issue as I can add an empty assets folder to the resource pack in the next update which will get around this limitation, but something like this might be a good feature to add.

Here's a version of my pack that has this issue:
Glowing Emissive Ores - v1.75.0 - Fusion

The resource pack requires fusion and another resource pack to work, which can be found in the description.

Or maybe even specifying the pack directly could bypass this limitation, so users could put this inside the config file and it would work:

[resourcepacks]
	required = ["global_packs/required_resources/", "resourcepacks/GEO - v1.75.0.zip", "resourcepacks/GEO - v1.75.0 - Fusion.zip"]

First time I hear of a mod doing that, feels kinda weird, idk whether packs loaded by global packs would work with that feature from Fusion, going to have test that.
Do you know any mods doing similar?

Actually I’m not sure if there are any other mods that do something like that, I assumed the “Resource Pack Overrides” mod did something similar but judging by the description it doesn’t, I haven’t tested it though.

I fixed it in the latest version by just adding an empty assets folder to the resource pack, I tested it, and it works correctly using this workaround.
