Will custom Image Effect and UI shader need to be upgraded for the new SRPs?

And if they are, how can I do that?

 

OK so I downloaded 2018.1 and it seems that my Image Effect doesn't work at all in the new SRPs - doesn't even show up in the frame debugger. Is a Custom Effect for the new Post Processing Stack is required now?

 

I did IE in PPS and it works fine, also remember it has some changes in shader to

 

So from now on all existing Image Effect will break?

 

Only in SRP (not in classic pipelines), OnRenderImage not work in SRP (as i think, because it has custom render logic).
But i think we can work outside PPS with CommandBuffer directly, because in PPS context we work with same CommandBuffer, for example you can use Blit from CommandBuffer in LateUpdate with Graphics.ExecuteCommandBuffer method.
Correct me if I was wrong somewhere.

We wrote it using this. You (for reasons clearly explained in the above doc) have to use a different approach. This is now the recommended way to make post effects for SRP.
