Class RTHandle
A RTHandle is a RenderTexture that scales automatically with the camera size. This allows proper reutilization of RenderTexture memory when different cameras with various sizes are used during rendering. RTHandleSystem
Namespace: UnityEngine.Rendering
Syntax
public class RTHandle

rtHandleProperties
Current properties of the RTHandle System. If a custom property has been set through SetCustomHandleProperties method, it will be used that one instead.
Declaration
public RTHandleProperties rtHandleProperties { get; }
Property Value
| Type | Description | 
|---|---|
| RTHandleProperties | 
scaleFactor
Scale factor applied to the RTHandle reference size.
Declaration
public Vector2 scaleFactor { get; }
Property Value
| Type | Description | 
|---|---|
| Vector2 | 
useScaling
Returns true if the RTHandle uses automatic scaling.
Declaration
public bool useScaling { get; }
Property Value
| Type | Description | 
|---|---|
| Boolean | 
Methods
ClearCustomHandleProperties()
Method that clears any custom handle property being set.
Declaration
public void ClearCustomHandleProperties()
GetInstanceID()
Get the Instance ID of the RTHandle.
Declaration
public int GetInstanceID()
Returns
| Type | Description | 
|---|---|
| Int32 | The RTHandle Instance ID.  | 
GetScaledSize()
Return the scaled size of the RTHandle.
Declaration
public Vector2Int GetScaledSize()
Returns
| Type | Description | 
|---|---|
| Vector2Int | The scaled size of the RTHandle.  | 
GetScaledSize(Vector2Int)
Return the input size, scaled by the RTHandle scale factor.
Declaration
public Vector2Int GetScaledSize(Vector2Int refSize)
Parameters
| Type | Name | Description | 
|---|---|---|
| Vector2Int | refSize | Input size  | 
Returns
| Type | Description | 
|---|---|
| Vector2Int | Input size scaled by the RTHandle scale factor.  | 
Release()
Release the RTHandle
Declaration
public void Release()
SetCustomHandleProperties(RTHandleProperties)
By default, rtHandleProperties gets the global state of scalers against the global reference mode. This method lets the current RTHandle use a local custom RTHandleProperties. This function is being used by scalers such as TAAU and DLSS, which require to have a different resolution for color (independent of the RTHandleSystem).
Declaration
public void SetCustomHandleProperties(in RTHandleProperties properties)
Parameters
| Type | Name | Description | 
|---|---|---|
| RTHandleProperties | properties | Properties to set.  |

Declaration
public static implicit operator RenderTargetIdentifier(RTHandle handle)
Parameters
| Type | Name | Description | 
|---|---|---|
| RTHandle | handle | Input RTHandle  | 
Returns
| Type | Description | 
|---|---|
