This page describes how to upgrade from an older version of the Universal Render Pipeline (URP) to version 11.0.x.

Upgrading from URP 10.0.x–10.2.x

The file names of the following Shader Graph shaders were renamed. The new file names do not have spaces:
```
Autodesk Interactive
```
```
Autodesk Interactive Masked
```
```
Autodesk Interactive Transparent
```
If your code uses the
```
Shader.Find()
```
method to search for the shaders, remove spaces from the shader names, for example,
```
Shader.Find("AutodeskInteractive)
```
.

Upgrading from URP 7.2.x and later releases

URP 11.x.x does not support the package Post-Processing Stack v2. If your Project uses the package Post-Processing Stack v2, migrate the effects that use that package first.

DepthNormals Pass

Starting from version 10.0.x, URP can generate a normal texture called

_CameraNormalsTexture

. To render to this texture in your custom shader, add a Pass with the name

DepthNormals

. For an example, check the implementation in

Lit.shader

Screen Space Ambient Occlusion (SSAO)

URP 10.0.x implements the Screen Space Ambient Occlusion (SSAO) effect.

If you intend to use the SSAO effect with your custom shaders, consider the following entities related to SSAO:

The
```
_SCREEN_SPACE_OCCLUSION
```
keyword.

Input.hlsl

contains the new declaration

float2 normalizedScreenSpaceUV

in the

InputData

struct.

Lighting.hlsl

contains the

AmbientOcclusionFactor

struct with the variables for calculating indirect and direct occlusion:


struct AmbientOcclusionFactor{    half indirectAmbientOcclusion;    half directAmbientOcclusion;};

Lighting.hlsl

contains the following function for sampling the SSAO texture:


half SampleAmbientOcclusion(float2 normalizedScreenSpaceUV)

Lighting.hlsl

contains the following function:


AmbientOcclusionFactor GetScreenSpaceAmbientOcclusion(float2normalizedScreenSpaceUV)

To support SSAO in custom shader, add the

DepthNormals

Pass and the

_SCREEN_SPACE_OCCLUSION

keyword the the shader. For an example, check

Lit.shader

If your custom shader implements custom lighting functions, use the function

GetScreenSpaceAmbientOcclusion(float2 normalizedScreenSpaceUV)

to get the

AmbientOcclusionFactor

value for your lighting calculations.

Shadow Normal Bias

In 11.0.x the formula used to apply Shadow Normal Bias has been slightly fix in order to work better with punctual lights. As a result, to match exactly shadow outlines from earlier revisions, the parameter might to be adjusted in some scenes. Typically, using 1.4 instead of 1.0 for a Directional light is usually enough.

Upgrading from URP 7.0.x-7.1.x

Upgrade to URP 7.2.0 first. Refer to Upgrading to version 7.2.0 of the Universal Render Pipeline.
URP 8.x.x does not support the package Post-Processing Stack v2. If your Project uses the package Post-Processing Stack v2, migrate the effects that use that package first.
