Get this after I make any scripting change at all. Please advise as having a pop up for this is irregular.
To clarify, I alter my own script, say - HelloWorld.cs and suddenly have to wait while HDRP decides if it still has it’s pants on or not.
2018.2 beta 7 with HDRP 2.0.3 (and earlier 2.0.1)
This is happening on me as well. Quite annoying 
Get this constantly on recent released 2018.2, can’t even close Unity - is starts to compile shaders again
I use HD Pipeline and after migration from 2018.1 I can’t do anything with my project except for seeing this popup message
Are you using the latest HD pipeline? it is available via package manager.
Yeah, in fact, it happened after I updated all the pipeline components. I update the core component first, which caused a lot of console errors (which makes sense, I guess), then I update the HD Pipeline component. After that I could easily get stuch in that poup window, and the only way out is to kill the process. I created an empty project with HD template and it works, although, it is really slow, not like HD on 2018.1, so I reverted to 2018.1 version, will wait for patches, because I need Shadergraph support.
Could it be because I updated the pipeline wrong? Is there any guides to do this?
You don’t need to ever update core, just the specific pipeline. Unity will select the correct core version.
I copied 2018.1 project and opened it in 2018.2.0f2, updated HD pipeline and got this:
A lot of errors and every surface is violet.
The core didn’t update, so I updated it manually and got this:
After that I can’t see any mesh at all, only standart unity gizmos (including custom OnDrawGizmo commands)
And everytime I move the editor camera, this error occurs:
Based on console log, the logics runs just fine, it just doesn’t render anything
Can’t include the project in bug report, because it’s pretty big
