EditorUserBuildSettings.overrideMaxTextureSize

説明

The override for the maximum texture size when importing assets.

This setting lets you override the maximum texture size in pixels that Unity uses when it imports assets. This is mostly useful for local development, to speed up texture importing or build target switching.

This setting affects all textures in your project, and overrides the import settings for individual textures. For example, if a texture's import settings indicate a maximum size of 2048 pixels, but overrideMaxTextureSize is set to 512, the texture will be imported at a size of 512 x 512 pixels.

Set this to a non-zero value to specify a maximum size that overrides individual texture import settings. Set this to zero to tell Unity not to apply an override, and to use the maximum size specified in individual texture import settings.

The Unity editor command line argument -overrideMaxTextureSize can also be used to set this.
