You should keep this on as disabling them will force FlightGear to calculate them at runtime. Normals Whether to export normals or not. UVs Whether to export UV texture coordinates or not. Apply Modifiers If you have any unapplied modifiers (like a Subdivision Surface Modifier), they will applied before exporting. Blender uses a +Z up convention (like FlightGear), but glTF forces +Y up as the standard. Data FlightGear does not yet support glTF cameras or punctual light sources, so you can disable eveything here. Limit to These parameters can be used to select which objects of your Blender scene will be exported. If none is selected, the textures will be in the same directory as the. Textures Optional directory where textures will be placed. bin + textures) has to be selected because FlightGear does not support loading embedded assets. Some important settings for the exporter include:įormat glTF Separate (.gltf +.

See the reference documentation in the Blender manual for more information about Blender and glTF. All textures attached to this node will also be exported correctly. You need to use a Principled BSDF to setup your materials so they can displayed correctly by FlightGear. The latest versions of Blender support glTF out of the box.

If you want to change the material parameters, you should do so in your 3D modelling software of choice (or manually editing the glTF file).Įxample settings for exporting a glTF model in Blender. Material animations don't work either for the same reason. As described earlier, Effects can't be assigned to glTF models because they use a predefined Effect that implements the material description of the glTF specification. In XML you can treat glTF models the same way you treat AC3D, with a few exceptions. FlightGear uses a different default material, which is specified in fgdata/Effects/model-pbr.eff.
When no material has been specified for a mesh, the glTF spec suggests using a 50% emissive grey material. Cameras and punctual lights are not supported. FlightGear provides its own system for animating objects, see Howto:Animate models. This includes skinning information like joints and weights, as well as the animation keyframes themselves. All parameters related to animations are ignored. Embedded textures are not loaded, so all textures must be saved to external files. FlightGear tries to adhere to the specification as much as possible, but there are some exceptions: All parameters and their default values are very well defined. The glTF 2.0 specification is the best resource when it comes to glTF. If your project uses custom shaders or requires special effects that cannot be handled by the standard PBR scheme (albedo/metalness/roughness), then you should be using AC3D files with custom Effects. The glTF specification is quite specific about how a material is defined, so it's not possible to add custom Effects to glTF models. However, this advantage can also be a disadvantage. what you see in Blender is exactly what you will see in FlightGear. This allows 3D models to have a consistent look across all software, i.e. glTF files contain PBR material information that is used by FlightGear to avoid messing with Effects manually like in the case of AC3D files. The main advantage of glTF is that PBR materials are handled automatically. Choosing which one to use for your project will depend on your requirements. Blender (.GlTF does not deprecate the AC3D file format as both can be used interchangeably, although each one has its own advantages and disadvantages. For example, Blender 2.49b lists 2.6.2, however 2.6.6 works just as well. The last number can be disregarded, but that is the version of Python you need. When Blender loads up, the console window will say something to the effect of "Compiled with Python version #.#.#", where each "#" is a number. Blender 2.49a for example requires Python 2.5, while Blender 2.49b requires Python 2.6. Unless otherwise noted, import and export requires the python version that your version of Blender uses. smd exporter, google "Blender smd export" For exporters, do a google search for "Blender export" where "" is the file extension you wish to export, minus the period. For importers, do a google search for "Blender import" where "" is the file extension you wish to import, minus the period. smd) can be supported with Python scripts. RAW Paste Data This is a 100% complete list of built-in Blender import and export file types/formats as of 2.49b (some file types/formats 2.5 support aren't listed here, but most are).
