Fix (project files) - workaround for C3 SDK issue

Created a quick workaround for the C3 issue mentioned in the last post. So, gltfPath with subfolders will work for both editor and runtime.

One caveat is that for the editor side to work, the final filename must all be different, even if stored in different subfolders.

Once the C3 issue is fixed, I will revert this change, so we can use the same filename in different subfolders.
