Multiple Passes in URP

[kohlhaas1808]

Hi,
I like to thank you for this amazing shader!
I like to ask you if it is possible to add more than one render feature?
I've added 2 Outline Features with differend layers. But only the first in the list is drawn.
Any ideas?
Thanks in advance

I've found the reason why it was not working with more than 1 feature.
The temporary Render Targets were not released before the second feature is called.
Thats because the methods called in the follwing order:

• AddRenderPasses->Feature_1
• AddRenderPasses->Feature_2
• Configure -> Feature_1
• Execute -> Feature_1
• Configure -> Feature_2 ( Here is the Problem, since the RenderTargets from Feature_1 were not released yet)
• Execute -> Feature_2
• FrameCleanUp -> Feature_1
• FrameCleanUp -> Feature_2

Here is my solution.
I call the release functions at the start of the Configure method.

public override void Configure(CommandBuffer cmd, RenderTextureDescriptor cameraTextureDescriptor)
{
    cmd.ReleaseTemporaryRT(objectsID.id);
    cmd.ReleaseTemporaryRT(blurredID.id);
    cmd.ReleaseTemporaryRT(tempID.id);
    cmd.ReleaseTemporaryRT(screenCopyID.id);

I tested this in Unity 2021.3.5f1 with URP 12.1.7
