## Definition

### Remarks

For volumetric render textures (see [RenderTextureDescriptor.dimension](/engine/6000.3/script-reference/unityengine/rendertexturedescriptor/dimension.md)), this variable determines the volume extent. Ignored for non-3D textures. The valid range for 3D textures is 1 to 2000.
