Asset Import Settings

Controls default behavior for imported assets.

note

These settings affect only you and global for the whole project.

Navigate to the ASSET IMPORT section and expand the panel:

Here is a breakdown of the available settings:

General

Setting	Description
Search related assets	If enabled, importing a source asset updates related target assets wherever they are located. If disabled, assets are updated only when in the same folder; otherwise, new assets are created.
Assets default to preload	Creates new assets with the preload option enabled. Script assets are always created with preload enabled.

Texture Import

Setting	Description
Textures POT	When a texture is imported, it will be resized to the nearest power-of-two resolution.
Create Atlases	If enabled, imported textures are converted to Texture Atlas assets instead of Texture assets.

Model Import

Setting	Description
Preserve material mappings	If enabled, when reimporting an existing source model, the Editor attempts to preserve existing user-defined material mappings.
Overwrite Models	When a model is imported, overwrites any previously imported model asset.
Overwrite Animations	When a model is imported, overwrites previously imported animation assets.
Overwrite Materials	When a model is imported, overwrites previously imported material assets.
Overwrite Textures	When a model is imported, overwrites previously imported texture assets.
Convert to GLB	Create model assets in GLB format.
Import Hierarchy	Generates a template asset when importing 3D assets (FBX, etc.). The template asset contains the full entity hierarchy from the imported file.
Mesh Compression	Specify the mesh compression to apply to imported models.
Unwrap UV	Generates a set of unwrapped UV coordinates.
Texels Per Meter	Specifies the number of texels per meter when UV unwrapping is enabled. Default: 16.
Import Morph Normals	Imports morph target normals when importing a model. Disable this if morph target normals look incorrect.
Create FBX Folder	Creates a new folder in the current directory when importing an FBX file to store the imported FBX contents.

Animation Import

Setting	Description
Naming Strategy	Choose the naming strategy for imported animations: Use Take Name: Name the animation after the take name assigned in the FBX file Use FBX Filename: Name the animation after the FBX filename
Sample Rate	The rate at which to sample animation curves (samples per second). Specify 0 to disable sampling and use input keys instead.
Curve Tolerance	The tolerance used when optimizing linear animation curve segments. Specify 0 to disable curve optimization.
Cubic Curves	Output cubic curves when they are encountered. Disable to convert all curves to linear segments.
