Compatible objects

Mirage impostors are compatible with any object that has a MeshFilter and a MeshRenderer attached. Translations (all axes), scaling (all axes) and rotation (around the vertical axis only) are supported.

Limitations

Due to their nature, Mirage impostors have a few limitations.

Full rotation compatibility

Impostors are not rotated around the X and Z axes even if their parent is.

Lossy scale

Mirage uses the lossyScale of the source objects. If the source objects are skewed by nested non-uniform scaling and rotation, the impostor may appear close to the source but unskewed.

Shadows

Mirage impostors are compatible with shadows, but they are not physically correct, since only the alpha-clipped quad is projected rather than a dedicated shadow pass. Shadows are correct when the light comes from the front or the back, but not from the sides of the impostor. This is a simplicity choice: a correct shadow would add a GPU-intensive shader pass, and shadows are usually not even visible from the impostor's nominal distance. It also keeps Mirage natively pipeline-independent, since Shader Graph is not yet designed to add custom passes.
