### Remarks

This represents a format for which the GPU can automatically do shadowmap comparisons for. Unity uses this format internally for shadows, when supported. Note that some platforms or GPUs do not support Shadowmap format, in which case shadows end up using [RenderTextureFormat.Depth](/engine/6000.0/script-reference/unityengine/rendertextureformat/depth.md) format.
