FBX Smart Material Conversion

FBX Smart Material Conversion is a feature of model importer, it can map some standard materials in DCC(Digital Content Creation) tools to Cocos Creator’s built-in materials, and restore the visual effects of materials in DCC tools. This feature was added in v3.5.1.

The following materials are supported:

Here is the comparison of a model using maya standard surface viewed in Maya and viewed in Cocos Creator after import:

You can refer to the following project file to see how the example model with Maya Standard Surface is imported. Maya Car Demo

Smart Material Conversion configuration and import process for FBX assets

1. In the Cocos Creator main menu, go to Project -> Project Settings -> Model -> Smart Material Conversion and make sure the option is enabled.
2. Select the FBX file in Cocos Creator, and make sure the Smart Material Conversion option is enabled in the Inspector panel of the FBX file.

The following is the final settings:
