	<!-- EDITOR NOTE: OUTDATED. Recent updates made shadows face the light, sample the light-facing atlas cell, handle self-shadowing, and stay stable across cascades. The "only correct from front/back" claim is no longer true. Rewrite this entry during the content refresh (no dedicated depth-written shadow pass was added, so keep the relevant caveats). -->

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.

= 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 [https://docs.unity3d.com/ScriptReference/Transform-lossyScale.html 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.
