Same here, getting

UE4 Unreal Engine 4 Steam sessions plugin does not work 4.27 - YouTube fix steam sessions plsss or tell me where i did fail thanks : D.
@VictorLerp @Amanda.Schade I have a feeling it’s no use at this point, but…
There is a big issue when building a project with streaming VTs for forward rendering Android Vulkan (ASTC):
vulkan.txt.txt (8.7 KB)
The gist of it:
UATHelper: Packaging (Android (ASTC)): LogWindows: Error: === Critical error: ===
UATHelper: Packaging (Android (ASTC)): LogWindows: Error:
UATHelper: Packaging (Android (ASTC)): LogWindows: Error: Assertion failed: CompressedFormat == PF_Unknown || CompressedFormat == CompressedMip[0].PixelFormat [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/VT/VirtualTextureDataBuilder.cpp] [Line: 676]
I figured it out (I think) and it’s just preposterous - project with VTs gets built when building Android ETC2, but doesn’t when building with Android ASTC… WTF… ASTC is what most phones support (the ones that don’t shouldn’t be even having projects with VTs built for them) and that’s the format Oculus recommends for Quest.
Case # 00346661 which was never turned into an Issue (at least not to populate Issues Tracker)
SteamVR seems to cause 4.27 to crash on start. When I uninstalled mine it works.
I’ve been looking into Bink. Big announcement with no documentation or tooling. You can create a bink media player and text that follows the same mediaplayer process.
There’s no way to encode a video to bink2 as far as I can tell. There is a commit that hints to adding Bink2ForUnreal.exe/pdf but the files are not in any repo or release. https://github.com/EpicGames/UnrealEngine/commit/220176c2e93823e42eca60e856b10e88a86869ba
Does anyone know where this is at? Not for general use?
After I built it as Android ETC2 and removed/regenerated mips from VT textures, it started building as Android ASTC 
I really wished Epic would use more defensive programming in UE.
If you’re on 4.27 working with sequencer and metahumans expect a lot of crashes.
I’m getting an index error crash and I assume hitting an asset. It would be nice if internally they checked the validity of values and tried to avoid letting it go until it crashes.

With a codebase this big, it’s more common to use offensive programming - put asserts all over the place, catch bad values as early as possible and stop the show to force other programmers to fix their underlying cause right away. Otherwise you’ll have a growing web of hidden issues that are compensated for by the defensive programming until it explodes completely.

Just wanted to say, for some reason adding diffuse boost to a object in lightmass baking will turn the scene into a nuclear reactor. Is this a bug?
That’s fine (asserts sprinkled in code) as long as they’re addressed. If they’re not addressed and result in a corrupt project that’s a problem.
Another example: 4.26 if you used an invalid file path for Movie Render Queue (easy to do if you change external hard drives or simply get preset from a friend for best render settings (the path is stuck in that info as well) the system would simply render each frame, post an error in the log and continue running for hours rendering nothing to a file.
A simple defensive check of user input values (such as an invalid file path) would be a much better approach. It could bring up Alert to the user that you’ve tried to provide an invalid file path, please correct (for the user)

For sure, it doesn’t make sense to use offensive programming against user input. More on internal stuff.
The UE5 Preview is Less buggy then this version… And Steam Sessions Actually work in it.
We ran into this issue as well, and it turns out that it’s due to a change in PostProcessComponent.h - previously it only checked the “bEnabled” flag, now it also checks SceneComponent()->ShouldRender(). ShouldRender() returns false when the post process component is attached to something that’s not visible - say, a player controller.
Our solution was to modify the engine to remove this change (in PostProcessComponent.cpp):
- Ret.bIsEnabled = bEnabled != 0;
+ Ret.bIsEnabled = bEnabled != 0 && ShouldRender();
E.g. back to:
Ret.bIsEnabled = bEnabled != 0;

we do it so they are aware of bugs we find. a bug report goes directly to the devs and without them they wont know you found a bug.

Another issue with 4.27 that we encountered in our Paper2D game is that tilemap editing breaks when a tilemap grows too large in the Y direction (too deep). When that happens, tiles cannot be selected or edited when viewing the tilemap with the default viewport Orthographic, Right).
After a lot of debugging we figured out that it was due to the raycast that figures out which tile is underneath the cursor doesn’t start from in front of the tilemap object. This means that the raycast always misses and nothing can be selected.
This happens when a tilemap grows to above 300-400 units deep in the Y direction. We have tilemaps with 12-15 layers, with 32 units of separation between each layer, so this happens for us with pretty much all our tilemaps.
Why does this happen? Well, the raycast starting position is determined based on the Bounds of the tilemap object (for some reason).
Our solution was to modify GetDesiredFocusBounds() in TileMapEditorViewportClient.cpp as so:
FBox FTileMapEditorViewportClient::GetDesiredFocusBounds() const
{
FBox Bounds = RenderTileMapComponent->Bounds.GetBox();
Bounds.Min.Y = 0.f;
Bounds.Max.Y = 0.f;
return Bounds;
}
This makes the raycast start from Y=0 regardless of the size of the tilemap, and now the raycast hits regardless of the size of the tilemap. 
UE-111807 seems to be fixed for 4.27.1-release (related commits were merged and the status says it’s fxed), but it is missing from that list and also says its target is 5.0 on the issue tracker.
WTF?
Steam is still Broken even after the Hot Fix. When will this be Resolved???

@Amanda.Schade It would be great to hear what’s going on with the Path Tracer and GPULM for AMD 6000 series cards. It used to all work on 4.26, now on 4.27/5 only realtime RT works. TDR settings don’t effect the DXGI_ERROR_DEVICE_HUNG that happens.
The Steam issues are also pretty severe. Broken Create Session BP node, SteamAuth kicking, SteamSockets.
I’ve tried submitting bug reports for everything.
