Sadly, all links to issues are incorrect

They're all updated!!!

4.20p1 still has huge memory leak and stuttering on a range of machines.

This one worries me. I suspect it's due to all the rendering changes in 4.19 for Temporal Upsampling etc...

Could it be this? https://issues.unrealengine.com/issue/UE-58673

Great update!

Digital Humans Improvements. A set of improvements targeted at both skin and eye rendering. Including dual lobe specular for skin, subsurface scattering for the eye material model and more.

Where can we find these updates? Are there any new example files or dcoumentation on this we can test with?

Has backscatter or "transmission" finally been added to skin?

The issue was introduced somewhere between 4.18.2 and 4.19.0 inclusively.
That ticket has the same symptoms, but It is not restricted to UMaterialBillboardComponent only.

The best summary that can be given is as follows:

Range activities on certain combination of hardware and software cause progressively deteriorating hitching and memory leak, both in editor and shipping configuration cooks.

It's baffling to see experienced cpp engine programmers somehow managed to introduce such massive memory leaks.

Any news on https://issues.unrealengine.com/issue/UE-51650 ?
Targeted fix is 4.20 but it doesn't seem to be in any of the lists

Loving the new changes! Noticed that the new cinematic depth of field looks great at 1080p but starts to have issues like this at higher resolutions: https://answers.unrealengine.com/que...nes-issue.html

Could someone please point me to the "list of supported webcams & HDMI capture devices" mentioned under VR/AR Updates? Thanks so much!

VR/AR Updates:

• Mixed Reality Capture: Early Access. The early access Mixed Reality Capture support has three components: video input, calibration, and in-game compositing. We have a list of supported webcams and HDMI capture devices that enable you to pull real world green screened video into the Engine from a variety of sources. ‘

Any news/documentation on Volume Textures? The Trello board suggested this was coming in 4.20...?

[FinalZer0]

Blaze it !!! Wanted to say that since 4.18. Great update btw

[silvermehran]

Wow finaly alembic and dof! thank Epic!

[BesuBaru]

Nice! Any update on dynamic resolution scaling on PC?

[Ninjin]

Also still having memory leaks. Did Epic even give a statement or something? Even your top Fortnite twitch streamers are forced to restart their whole game after a couple of matches.

Yes, transmission is added for dynamic lights. I just opened their photoreal character example in 4.20.

Thanks I can see the hook in the lights but it's a barely noticable effect on the skin. There's also no hook in the skin shader for transmission? Backscatter as it was previously listed is purely for the soft top level SSS not true backscatter or transmission as Epic call it now. I hope on full release their will be indepth documentation.
