Dear Friends at Epic, The situation here is a little complicated. I made a node in my VictoryBPLibrary plugin so that people can get a list of available screen resolutions in Blueprints, as this functionality does not seem to be in blueprints. The BP node works great in pre-shipping builds! Everyone has confirmed that. But when the game is packaged, even with the appropriate Build CS public dependency additions of **RHI** and **RenderCore** , the node does not work! The game packages just fine, but in both Development and Shipping packaged builds, the node does not work! #Build CS Clarity Just to be clear, in my very own project where I had to be able to compile the CPP version, by adding the RHI public dependency, it is this same project that I added the BP plugin version that is not working. So it is not a Build CS issue, since I compiled both the CPP and the BP plugin and Packaged all using the same Build CS #CPP and BP Versions Tested About 1 Second Apart, Only 1 Works I did the following: I composed a CPP test in a packaged game that activates on key press. I also included my own blueprint node as part of my plugin, included with the packaged project. When I press the key to test the BP node, it returns false. **As you can see in code below, that means that RHIGetAvailableResolutions itself is returning false!** Then I press the key to run the CPP version, and it WORKS !! Somehow the BP node usage of RHIGetAvailableResolutions is returning false, while in the same exact test, about 1 second later, then CPP version returns true, and spits out all my computer’s screen resolutions! How is this possible? #Repro If you’d like to test my Plugin version yourself, you can download my plugin here! > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline.

This is duplicate! continue; } else { //Add to Unique List! Unique.AddUnique(Str); } //Add to Actual Data Output! VShow(Str); } } else { VShow("RHIGetAvailableResolutions returned false!!!!!!"); } } ``` #BP Node In Editor Builds, this works perfectly! **In a packaged game it returns false!!!** (tested by me and Midnight on different computers, for both dev and shipping packaged game) **This means that RHIGetAvailableResolutions itself is returning false within the BP node code, for some reason!** ``` bool UVictoryBPFunctionLibrary::OptionsMenu__GetDisplayAdapterScreenResolutions(TArray& Widths, TArray& Heights, TArray& RefreshRates,bool IncludeRefreshRates) { //Clear any Previous Widths.Empty(); Heights.Empty(); RefreshRates.Empty(); TArray Unique; FScreenResolutionArray Resolutions; if(RHIGetAvailableResolutions(Resolutions, false)) { for (const FScreenResolutionRHI& EachResolution : Resolutions) { FString Str = ""; Str += FString::FromInt(EachResolution.Width); Str += FString::FromInt(EachResolution.Height); //Include Refresh Rates? if(IncludeRefreshRates) { Str += FString::FromInt(EachResolution.RefreshRate); } if(Unique.Contains(Str)) { //Skip! This is duplicate! continue; } else { //Add to Unique List! Unique.AddUnique(Str); } //Add to Actual Data Output! Widths.Add( EachResolution.Width); Heights.Add( EachResolution.Height); RefreshRates.Add( EachResolution.RefreshRate); } return true; } return false; } ``` #The Ultimate Goal My real goal is to give BP users the ability to get a list of all screen resolutions without having to use CPP / have a c++ programmer on their team! Any ideas? And why would RHIGetAvailableResolutions work - in BP in Editor Builds - In CPP all the time and not work in a packaged game as a BP node? #Thanks Thanks! This issue isn’t really something that affects me, I am trying to help everyone else with this one. ---

Thanks for posting in such detail. All I can say is my config in which the plugin **did not** work: - 2x GTX570 in SLI 1 monitor active 2 disabled - SLI OFF 3 monitors active (not surround) - SLI OFF 1 monitor active 2 unplugged - NV SURROUND 3 monitors as one In all the cases the plugin worked when playing in editor ! ---

Hi , I have sent this information to the development team for further investigation. I hope to hear back from someone there soon regarding this issue. ---

#Epic? I got 's initial response but I’ve heard nothing since, any update on this? Why RHI get resolutions is not working when called from BP in a packaged game? You can use my Victory BP Library to test this!

or just integrate it. Even in your livestream [- YouTube](https://www.youtube.com/watch?v=FaBJYFhP5yo&list=UUBobmJyzsJ6Ll7UbfhI4iwQ) people think this could be useful. ---

#Resolved I have tested and in 4.4 this issue has been resolved! I can now call RHI Get Screen Resolutions in a BP node in a plugin, in 4.4! It works great! Thank you Epic! #❤ #Download Here is the version of my plugin that I tested in a packaged game where it worked great: August 16th, 15:38AM 2014 ---
