class omni.flux.utils.material_converter.MaterialConverterCore#

Bases: object

async static convert(
context_name: str,
converter: ConverterBase,
) → Tuple[bool, str | None, bool]#

Convert the material

Parameters:

  • context_name – the context to use

  • converter – the converter to use

Returns:

Success, message, skipped or not

async static find_matching_supported_material(
input_shader_prim: Usd.Prim,
) → Tuple[ConverterBase | None, _SupportedShaderInputs | None]#

Find the matching supported material from all inputs. It can happen that inside a MDL, a supported MDL is imported and some attributes are set. But the MDL is not supported. So to check if this is really supported, we check if the attributes are matching with a supported MDL
