Given a folder structure that looks like this: tank_tanker_V0.2.gltf tank_tanker_V0.2.bin tex_tank_default_concrete_n.png ... // additional textures When I upload these to gltf.report and then export in binary format, this gets changed to: tank_tanker_V02-v1.glb. More problematic is that when I export in JSON format, I get: tank_tanker_V02.gltf tank_tanker_V0.2.bin ... // textures unchanged If I add even more dots so that I have: tank_tanker_V0.2.1.1.1.1.gltf tank_tanker_V0.2.bin Then I can no longer export at all and I get the error message: Provide file name, without any extension. Name must contain only alphanumeric, underscore, and dash characters.
