Parameters

Type	Name	Description
IGltfWritable	gltf
ImageExportBase	imageExport
Int32	textureId

Returns

Type	Description
Boolean	glTF texture ID

ConvertMaterial(Material, out Material, IGltfWritable, ICodeLogger)

Declaration

public abstract bool ConvertMaterial(Material uMaterial, out Material material, IGltfWritable gltf, ICodeLogger logger)

Parameters

Type	Name	Description
Material	uMaterial	Source material
Material	material	Resulting glTF material
IGltfWritable	gltf	glTF to export material to. Will be used to add required texture images
ICodeLogger	logger	Custom logger

Returns

Type	Description
Boolean	True if material was converted successfully, false otherwise

Implements
