Unreal Engine 4.26 Preview

Thank you very much, we are waiting for updates )

“Mobile rendering improvements” - 4.25 have a crash on Android as soon as we using any number of Custom Data on Instance. Hope this will be fixed?

The physics is totally glitched ! My project is based on physics. I’m very scared about Chaos …
Even a simple Skeletal Mesh who simulate physics is terrible.
Constraints doesn’t works any more ( Constraints on mesh details )

I was using 4.24 for a long time now and was pretty happy with it but i decided to give 4.26 a try because of gpu lightmass, some of the things i’m saying might be changes from 4.25 that i don’t know about.

I can’t disable realtime viewport, the checkbox is disabled! there is a new button “disable realtime override” and it doesn’t do anything.

PlaceActor window doesn’t show up with hotkey!, i always closed the Modes\PlaceActor window and used shift+1 hotkey to open it up when i need to add a new light or actor to my scene but now it just doesn’t work, i should either leave the window open or go to menus everytime to open it up.

May I know what is Extended translucency support in raytracing. I don’t see any difference between 4.25 :frowning:

How to make a character’s hairstyle collide not only with the character but also with other characters and objects? It is very annoying that the strands fall into the meshes and underground!

4.26 use plugin ‘hololens media player’ ,there is screen flickering bug

The bug report seems to be broken, so here’s the report here - setting AO intensity to 1 disables sky lights.

because i don’t see it in 4.26 or it is broken?

that’s one of Ryan Brucks’ experiments. it’s been there for 2 or 3 UE4 releases and some of it derivated into the new Water plugin, but that’s really not it

Its by default built in now, launching its going to be chaos unless you specifically use the physx interface override instead, its also very very unstable currently as its still being heavily iterated on (from git commits). Kind of surprised that 4.26 P1 was put out before some more polish passes on it tbh, guess its going to be a long series of previews.

oohh it might mean Chaos (the physics engine) is there and replacing PhysX but maybe Chaos Destruction isn’t there. to get Destruction you need to activate a plugin, so maybe that’s the missing part. or maybe indeed the Destruction still needs a custom engine build

How would you re-enable PhysX? Found PHYSICS_INTERFACE_PHYSX definition in the code… Hope it doesn’t require a custom built engine.

Hey there’s no 4.26 option in the dropdowns for bug reporting on either the public submission page or UDN (unsure if it’s normally there before actual full release or not). Should we be using N/A for now and put 4.26p1 in the title or something? Ex. https://udn.unrealengine.com/s/quest…L00004nVOBpSAO

Will there be any media framework updates with release at all?

Or all towards 5.0?

those are compile defines, so yes that will require a custom built engine

I think Chaos replacing PhysX is great! But I see many bugs right now: physical handle component is broken, attach/detach physics actors is broken too, etc. I made a twitter thread of what I found so far, with videos: https://twitter.com/games_inu/status…35036509368320

Btw, the project is just the third person template from launcher, no change to anything in project settings/editor settings.

When searching for the new water stuff under “Plugins” I (for the first time) noted the “Virtual Heightfield Mesh” plugin? Is that new? What does it do (couldn’t find any documentation)?

Hello,
Fog on hair is still not working like in 4.25.x, hope it will be fix soon.
Does anyone have this problem ?

No, Chaos destruction is on Preview version. And it’s work. Not really well, but it’s works.

( And it’s activated by default )
