| path | The path of the Asset whose artifact should be the dependency. Note: Although the dependency is the artifact (import result) which is stored in the library folder, this parameter is the path to the Asset in the Assets folder, and not a path to the artifact in the Library folder. |
| guid | The guid of the artifact dependency. |
| key | The artifact key of the artifact dependency. |
Setup artifact dependency to an asset.
An artifact dependency is a dependency where an Asset depends on the import result (known as an artifact) of another Asset. If you change an Asset that has been marked as a dependency, all Assets which depend on it will also get reimported (after the dependency has been imported).
Note: If you specify an Asset as a dependency that doesn't exist or hasn't yet been imported, the dependency is still registered. It is registered as an un-imported Asset. When the Asset is later imported, all Assets which depend on it will also get reimported.

if (texture != null) { var textureInfo = ScriptableObject.CreateInstance<TextureInfo>(); textureInfo.height = texture.height; ctx.AddObjectToAsset("TextureInfo", textureInfo); } } }
