I would like to know if Gdevelop supports files that are not GLB for 3 Dimensional objects. Does it support bbmodel files from blockbench, and if no, what software allows me to create 3D models in GLB format, or convert bbmodel files to glb format.
i can at least answer the first question. Only GLB is supported.
Not super familiar with blockbench at all, but from some googling it doesn’t seem like it supports anything that does conversions directly.
However, blockbench’s site mentions it has .obj and gltf support. If you can export to ob or gltfj, you should be able to import into most other tools that support glb, and there even seems to be dozens of online converters.
