Is there a way in Godot 4 to load textures at runtime from outside the
res:// file system without importing them into Godot beforehand?
I've already tried a lot, but somehow I can't get any further and either get the error that resources have to be imported beforehand or, in the case of DDS textures, the error: Unrecognized or unsupported color layout in DDS.
Edit: External textures added for completeness can be loaded in both 3.5 and 4 as dds with the
ResourceLoader. I had good results with the BC1/DXT1 format without mip maps.
For example, textures created under Godot 4 can be packed into a resource package with the
PCKPacker at runtime, which can then be loaded at runtime and the dds textures contained therein can be used.
