Class Importer.AdditionalLoadingOptions

Represents additional options that control the behavior of asset loading, such as texture compression, mipmap generation, and memory optimization strategies. This struct allows fine-tuning of import-time features to balance between performance, memory usage, and visual fidelity.

Syntax

public class Importer.AdditionalLoadingOptions

Remarks

You can create an instance of this class and pass it to the ImportFromFile, ImportFromFileAsync, ImportFromStream, and ImportFromStreamAsync methods of the Importer class.

Fields

CompressTextures

Determines whether textures are compressed during import to reduce memory usage. If true, textures are compressed using the quality specified by CompressWithHighQuality. If false, textures remain uncompressed. Defaults to true.

Declaration

public bool CompressTextures

Field Value

Type	Description
bool

Remarks

This option increases the importing time when enabled.

CompressWithHighQuality

Specifies the quality of texture compression when CompressTextures is true. If true, high-quality compression prioritizes visual fidelity. If false, lower-quality compression optimizes for smaller file sizes. Defaults to true.

Declaration

public bool CompressWithHighQuality

Field Value

Type	Description
bool

Remarks

This option increases the importing time when enabled.

GenerateMipMaps

Determines whether mipmaps are generated for textures during import. If true, mipmaps are created to improve rendering performance and quality at varying distances. If false, mipmaps are not generated to save memory. Defaults to true.

Declaration

public bool GenerateMipMaps

Field Value

Type	Description
bool

Remarks

This option increases the importing time when enabled.

MakeMeshesNoLongerReadable

Determines whether meshes are marked as non-readable after import to reduce memory usage. If true, meshes are non-readable, preventing CPU access. If false, meshes remain readable, increasing memory usage. Defaults to true.

Declaration

public bool MakeMeshesNoLongerReadable

Field Value

Type	Description
bool

MakeTexturesNoLongerReadable

Determines whether textures are marked as non-readable after import to reduce memory usage. If true, textures are non-readable, preventing CPU access. If false, textures remain readable, increasing memory usage. Defaults to true.

Declaration

public bool MakeTexturesNoLongerReadable

Field Value

Type	Description
bool

MaxThreadStall

Defines the maximum time (in milliseconds) the main thread can be stalled before yielding. Defaults to 33ms.

Declaration

public int MaxThreadStall

Field Value

Type	Description
int

Remarks

Only works with asynchronous import methods.

TextureFilterMode

Specifies the filter mode for imported textures, controlling sampling behavior. Affects texture quality when mipmaps are enabled (see GenerateMipMaps). Defaults to UnityEngine.FilterMode.Trilinear for smooth mipmap transitions.

Declaration

public FilterMode TextureFilterMode

Field Value

Type	Description
FilterMode
