Supported formats

Fyrox supports these file formats for 3D models:

  • FBX
  • RGS - native scenes format produced by Fyroxed

Material import

The engine tries to import materials as close as possible to originals in the model, however it now always possible because some 3D modelling software could use different shading models. By default, the engine tries to convert everything to PBR materials, so if you have a 3D model with a special material made for cartoon shading, the engine will still import is as PBR material (with lots of missing textures of course). You should take this into account when working with something other than PBR materials.

In cases when your 3D model have some weird materials, you should create appropriate materials and shaders manually, the engine is not a magic tool, it has some defaults that do not cover all possible cases.

It is also possible to specify how to resolve textures while loading a 3D model, to do that you need to create import options file with the following content near your 3D model:

(
    material_search_options: RecursiveUp
)

The file must have the .options additional extension. For example, if you have a foo.fbx model, the options file should have foo.fbx.options name. Even if it is possible to modify it by hand, it strongly advised to use the editor to edit import options, because it reduces chances to mess up something.

Tips for Blender

Blender's FBX exporter has exporting scale properties usually set to 100%, this may lead to incorrect scale of your model in the engine. It will have (100.0, 100.0, 100.0) scale which is very huge. To fix that, set the scale in the exporter to 0.01.

Tips for 3Ds Max

Latest versions of 3Ds max have node-based material editor which creates some "junk" nodes which may mess up material import. To prevent any issues with that, you should clean all assignments to material slots to use maps directly.
