Loading external COMPRESSED gltf files

Hi, we’re very close to finish our proof of concept development, and we’re now getting into files and textures optimization. Our configurator setup includes a main gltf file and several dummy external gltf files, each of which include just a plane mesh with just a material applied to it.

So, when we need to apply a different material to an object, we load the corresponding dummy gltf file into the scene with “append scene” puzzle, and when it is loaded, we copy over the material from the loaded mesh to the desired object.

While this worked perfectly for “regular” gltf files, we cannot make it work with LZMA compressed files. We can load the main gltf.xz file without problems, but we’re not able to load the xz files for the dummy files. We get errors in the console, like this:

Cannot enlarge memory arrays. Either (1) compile with -s TOTAL_MEMORY=X with X higher than the current value 16777216, (2) compile with -s ALLOW_MEMORY_GROWTH=1 which allows increasing the size at runtime but prevents some optimizations, (3) set Module.TOTAL_MEMORY to a higher value before the program runs, or (4) if you want malloc to return NULL (0) instead of this abort, compile with -s ABORTING_MALLOC=0

In fact, all the examples in the documentation for both “append scene” and “load scene” puzzles have their examples with files that go like “path/to/scene.gltf”.
But it seems that specifying a file that includes the xz extension isn’t working. Oh, and by the way, we already have the option “compressed assets” enabled at the Init category for the puzzles.

Any ideas of what we may be doing wrong? Thank you!
