| [DeviceSpecific](/engine/6000.7/script-reference/unityengine/vrtextureusage/devicespecific.md) | The texture used by an external XR provider.  The provider is responsible for defining the texture's layout and use.                                                                                                    |
| [None](/engine/6000.7/script-reference/unityengine/vrtextureusage/none.md)                     | The RenderTexture is not a VR eye texture. No special rendering behavior will occur.                                                                                                                                    |
| [OneEye](/engine/6000.7/script-reference/unityengine/vrtextureusage/oneeye.md)                 | This texture corresponds to a single eye on a stereoscopic display.                                                                                                                                                     |
| [TwoEyes](/engine/6000.7/script-reference/unityengine/vrtextureusage/twoeyes.md)               | This texture corresponds to two eyes on a stereoscopic display. This will be taken into account when using [Graphics.Blit](/engine/6000.7/script-reference/unityengine/graphics/blit.md) and other rendering functions. |
