Hi,
Are those minimum or strictly those requirements?
This is a desperate question to hopefully save my old projects and merge them over to 4.22.

Cheers

Are we ever going to have the ability to render out of Sequencer with an alpha channel ? One that takes in to account additive materials ? Am I missing something - how are you being at the forrefront of film productions when you can't render out an alpha channel - I don't get it . I just went into 4.22 and rendered out anything that could work and the opacity is completly black - I made 2 materials one additive and one transpartent with a fresnel and only the translucent material showed up in the transluecent layer but black in the opacity ??? Why

Did you use the Composure plugin? It's supposed to separate stuff like you seem to want to.

Hi.

I encountered the following issue:

When I'm packaging the game for IOS in Shipping from Editor and I have the "Support bitcode in Shipping" option enabled the build fails with the following error:

ld: bitcode bundle could not be generated because '/Users/user/UE4/Builds/SKU1112/D/Engines/UE4/UE_4.20/Engine/Source/ThirdParty/mtlpp/mtlpp-master-7efad47/lib/IOS/libmtlpps.a(command_buffer_fence.o)' was built without full bitcode. All object files and libraries for bitcode must be generated from Xcode Archive or Install build
file '/Users/user/UE4/Builds/SKU1112/D/Engines/UE4/UE_4.20/Engine/Source/ThirdParty/mtlpp/mtlpp-master-7efad47/lib/IOS/libmtlpps.a' for architecture arm64

I'm building on Windows with configured remote Mac. When the bitcode option is disabled everything works fine.

It seems the thirdparty has been built without bitcode support. I'd be nice to get this file to be able to build with the bitcode

This issue seems to exist in 4.21, also.

Hi, I have a problem with updating plugin from 4.19 to 4.20 version.

(484): error C2248: 'UWorld::StreamingLevels': cannot access private member declared in class 'UWorld'

I haven't used that particular variable, but I have other code that accessed ex-public members.
In all my cases I found out Epic replaced the direct access for a getter method. And searching the docs I found one for StreamingLevels as well, that returns exactly the type you declared there, but constant. So just change that line into

const TArray<ULevelStreaming*>& Levels = World->GetStreamingLevels();

and it should work.

Hi, I have a problem with updating plugin from 4.19 to 4.20 version.

This is 4.19 code:

483: TArray<FString> Streaming;
484: TArray<ULevelStreaming*>& Levels = World->StreamingLevels;
485: for(ULevelStreaming* EachLevel : Levels)
486: {
487: if(!EachLevel) continue;
488:
489: FString NoPIELevelName = UMySaveLibrary::RemoveLevelPIEPrefix(EachLevel->GetWorldAssetPackageName());
490:
491: Streaming.Add(NoPIELevelName + FString("=") + BOOLSTR(EachLevel->IsLevelVisible()));
492: }
493: Ar << Streaming;

Here is the log:

(484): error C2248: 'UWorld::StreamingLevels': cannot access private member declared in class 'UWorld'
H:\Games\Epic Games\UE_4.20\Engine\Source\Runtime\Engine\Classes\Engine/World.h(796): note: see declaration of 'UWorld::StreamingLevels'
H:\Games\Epic Games\UE_4.20\Engine\Intermediate\Build\Win64\UE4Editor\Inc\Engine\LevelStreamingKismet.generated.h(12): note: see declaration of 'UWorld'

I know that in 4.20 version is changed functions for level streaming, but I don't know which one I need to use.

Thanks in advance.

I'm brand new to the forum and I don't know how to start a new topic.
I started writing a message and then was denied with private message quota exceeded (and that was the first thing I ever wrote)

I tried installing Unreal Engine on my Win10 PC, 6-core i7 8750, GTX 1060-6gb VRAM, 16gb 2666MHz RAM, and Nvidia driver Version 416.34 Release Date: 10.11.2018

but I received an error message saying "Unsupported Graphics Card, There is a problem with your graphics card. Please ensure your card meets the minimum system requirements and that you have the latest drivers installed."

Any help with this issue would be greatly appreciated.

Oddly, I can still play and the weapon parts show up. I submitted a crash report with the log/dump.

P.S. I've just fixed my case by redoing my (still prototype) weapons from scratch to not use ISM components. But some may not be so lucky.

If anyone has bumped into the PhysicsSerializer warnings as I did: opening related BP, refreshing all nodes, and saving fixed those for me.

Is it possible to scale the HLOD transition distance in 4.20? The old cvar is gone, and it seems like the only option is to override it to a specific distance.

[SmashedIt]

this is good
