Editor and game freezing

I have 2 rooms with two postprocessingvolume which have different cubemap. When I fly or go in game through junction ue4 freezes at all

Hey landgraf paul,

Could you provide me with some screenshots and some steps so I can reproduce this is a clean blank project with minimal assets?

Could you also provide me with your ‘dxdiag’ so I can take a look at your system specifications?

Thank you,

Yes, I made a video for you UE4.12 freezing issue - YouTube

I just attempted this in a new blank project and could not get the crash to occur. If you could please provide me with the information requested in my initial line of questions, we can move forward with the reporting process. It was hard for me to tell, but is the freeze/crash bringing up a Crash Reporter dialog window?

If so, could you please provide me with the logs from your project’s content directory in order to further investigate the crash?

Thank you,

Because your game freezes and you mention cubemaps, I think your issue may be the same as mine. I found a bug in the engine source that causes an infinite loop in certain conditions when using cube maps. I posted about it here: 4.12 infinite loop in engine source + fix - C++ - Unreal Engine Forums

landgraf paul can you check whether using cube maps or not makes a difference? If the issue occurs only with cube maps, then I am certain that we encountered the same bug. I described the fix in my post! Unfortunately I don’t have my machine set up to do pull requests, so if anyone else could do the fix?
