Unreal Engine 4.19 Released

[Nexus-studio]

There was a problem with the Linux compilation.
Here is the error: clang-5.0: error: invalid linker name in argument ‘-fuse-ld=lld’

@Nexus-studio

There was a problem with the Linux compilation.
Here is the error: clang-5.0: error: invalid linker name in argument ‘-fuse-ld=lld’

Problem solved by installng lld. sudo dnf install lld

What’s the right way to query which VR module is in use now? In 4.18 I used this:

if (GEngine->XRSystem.IsValid() && GEngine->XRSystem->GetHMDDevice() && GEngine->XRSystem->GetHMDDevice()->GetHMDDeviceType() == EHMDDeviceType::DT_SteamVR)

GetHMDDeviceType seems to have gone away.

edit: it seems to be

GEngine->XRSystem->GetSystemName()

[OverRated_AU]

Bug Fix: Removed the Inverse Lerp node and redirected it to Normalize To Range. Also Fixed incorrect value being returned by Normalize To Range when Range Min and Range Max are equal.

Why has this been removed then changed to Normalize To Range? they don’t even have the same behavior.

@The_Distiller

It is indeed missing. Epic please fix this ASAP.

Can confirm this as well. Folders are nowhere to be found.

If you’re using VR, It’s just outside of the visible area.

Yes i use VR how i can set the position?

[Sean_L]

@3dlight

Engine\Extras\MayaLiveLink\ doesn’t exist, or do I have to download and build from github? I installed fresh from Epic Launcher and the Maya Live link plugin path mentioned in the notes doesn’t exist.

Thanks for pointing this out. I’ve logged a ticket for this, which you can track here: Unreal Engine Issues and Bug Tracker (UE-56175)

Have a great day

[motorsep]

@Mallory85

Command “stat fps” dont work

Report using proper bug report system. There is no way to set position for the counter and I didn’t have any issues seeing stat fps counter in VR using 4.19 preview 5 (didn’t use pre6 in VR).

[anonymous_user_41845f4a]

@Hevedy

I reported a problem with the landscape, but after see Epic put a image of the new landscape and can’t see themselves that is total terrible I won’t report any more it. In the image you posted and as in all new landscapes all the LODs 0,1,2,3 are collapsed in the same zone as you can see from the image:
https://dnnrz1gqa.blob.core.windows…rBZj7Oiaxxo%3D

https://dnnrz1gqa.blob.core.windows…e3KauNBCMCo%3D

And this is total bad for performance, as even the LOD0 go up km or lots of m before go out. As you can see all the LODs are collapsed.

But I imagine this is a update for Unreal Studio and Cinematics so whatever

Hello @Hevedy ,

Thank you for your report, however, please submit a bug report to our Bug Submission Form so that we can take a look and enter it into our database if we are able to reproduce it.

Edit: I apologize, I just saw that you have already reported this. If it was through the form linked above, please let me know the exact name of the report you sent and I will search for it and check the status of the report.

[Sean_L]

Since the Submission Form seems to be useless (submitted this crash 3 times in three different Preview Versions)
The Editor crashes when I try to type something into the console.

Hi @Raildex_

The issue exists in our public database. You can find it here: Unreal Engine Issues and Bug Tracker (UE-54215)

However, we’re currently looking for a way to reproduce this crash, so if you do have solid repro information that we can try, please let me know and I can update the ticket.

Thanks

SpeedTreeColorVariation/PerInstanceRandom is still outputting NAN/garbage starting with 4.19. Entire forests are rendering black in Epic’c most Epic, Kite Demo… Doesn’t Epic care about that anymore?

still crashing using vive motion controller since preview 5, before that everything was fine. Is there something to do with this new motion controller live link thing?

@Daelus

Not sure if I’m missing something, but it seems like light shapes are broken for lightmass. Create a point light, set it to static, and give it a radius and length, and bake it and it comes out rotated 90 degrees. Happens in a freshly created project.

Hello @Daelus ,

The signature changed to add const and pass the array by reference, just update your method signature to match, eg:

I have multiply material instances with parameters that have been lost when updating from 4.18.2, also there not saving properly ether in 4.19 closing the engine down and restarting my project these parameters get reset, it seem this new saving feature has bugged out the standard saving.
