Unreal Engine 4.20 Preview

[anonymous_user_ea753896]

I cannot figure out the Blutility Context menu functionality.
I created an Actor Action Utility (from contentbrowser rightlick -> Blueprints -> Blutility), but it just shows an empty list “New Editor Utility Blueprint 1Actions” and there is no options, no buttons, no other tabs. Did anybody figure this out? Am I experiencing a bug?

Also, in my opinion, this should be handled exactly like “call in editor” on custom events, instead. You should have a tickbox under “call in editor” that is “list in menu” and if that is on, you get that event listed in the context menu of that actor. Or maybe I misunderstand how this thing is supposed to work in the end.
I also want a “call in editor” functionality for keypress events, so you can make blueprints run in editor time via button presses. Possibly even without selecting the blueprint tool.

Any advice?

I’m using branch as well. (It also has UE4PrereqSetup_x64.exe and it does work)
Also, it’s only affecting Launcher. Since I could run UE4Editor.exe.

@Max.Chen

To set the start/end ranges, you can either scrub to the frame you want and hit the shortcuts or ]. Or you can type the numbers into the menu.

: ) I missed that, it’s because I always right clicked and tried “set start or end time” and that never worked, the bar kept snapping to previous frames, I only assumed this would do the same.

As for the shortcuts: I could swear those were missing last i checked the docs days ago for the start/end frames.

Thanks though.

How about implementing bookmarks/favorites in material editor with even varied colors for differentiation, so that we do not have to scroll long to find what we need?

[maxbrown]

@S-ed

Any advice?
…
I’m using branch as well. (It also has UE4PrereqSetup_x64.exe and it does work)
Also, it’s only affecting Launcher. Since I could run UE4Editor.exe.

Maybe have a look at your antivirus program. I had a similar error and it was due to Bitdefender that flagged one install file as a virus. Adding the UE folder to the whitelist fixed this for me.

Is there a special way to activate these?

• Occlusion Queries on Mobile
• Software Occlusion Culling

As a mesh I placed behind another mesh was not being culled and counted as a draw call on my Android device. Or did I misinterpret what is meant to happen with these features?

4.20 P1
Android S8 8.0.0

@FS_Creations

I would like to know . I’ve been doing some tests and occlusion in mobile doesn’t seem to be any different from 4.19 (i.e. it doesn’t work at all except for frustum culling or precomputed visibility volumes)

Thanks!

Perhaps it’s not supported in mobile VR ?

Testing again I did in fact get this working! It works when you export using openGL 3.1 !

I also tried Vulkan but it was a mess - the meshes behind were always popping in and out

I also tried GearVR and it worked there as well. However very occasionally I did also notice a small pop in and out from the meshes behind the mesh that was in front of it so it still seems just a little buggy?

Once this is reliable this will be HUGE for mobile VR! Out of interest does anyone know if Unity already supports this?

PS: A nice little side note - android build times seem much faster in 4.20!

I cannot found the New DOF in Editor, does someone know where is it hiding?

Use the CircleDoF, it’s been completely replaced

[zeOrb]

@stanrealvisual

I cannot found the New DOF in Editor, does someone know where is it hiding?

There is an option “Use new DOF algorithm” in Project settings - Postprocessing, however it’s enabled by default so just play with settings of CircleDOF and you will see the difference immediately

[ZacD]

I was using the cinematic camera to play with the new DoF. Not sure if there’s a big difference.

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. ‘

Yes, please! More info on what capture hardware is supported would be very appreciated. Some documentation on how to set up calibration would also be useful.

hi, it´s time for an noobish question:

when i click on library /engine-Versions/+, there is no ue4.20 preview avaiable… where can i find the download?

thanx for an answer

[RVillani (Rod Villani)]

@loopon

The + button is like “I want a new one”. But you choose the version clicking on the version number before installing.

[RVillani (Rod Villani)]

@aussieburger

I did also notice a small pop in and out from the meshes behind the mesh that was in front of it so it still seems just a little buggy?

Not buggy. That’s just how hardware occlusion works. The video card analyzes the last frame’s depth and decides what was occluded. So if something has just become visible, it will only not be occluded on the next frame. Hence, on quick camera movements you can see that popping. Software occlusion, on the other hand, is instant, but consumes CPU cycles.
Choose your trade-off.

Hmmm I’m not sure what you are saying applies to mobile and the current state of Unreal? Mobile Hardware does not support occlusion afaik hence the reason 4.20 adds software occlusion. I see the popping without moving the camera at all.

Additional findings:

• For OpenGL 3.1 it’s not possible to disable the software occlusion? Due to the aforementioned bug this means we can no longer build Mobile VR with OpenGL 3.1
• When I tested this with **Multiview ON **the meshes are not rendered at all! (building with multiview on, opengl 2 and the meshes are rendered but no software occlusion).

Any updates from Epic in regards to:

• When mobile software occlusion will work with Multiview?
• How much of a CPU hit mobile occlusion is?

When doing a quick google on Unity support it appears they have supported mobile occlusion for a long time now however the CPU hit is very high. Would be great to compare this to the Unreal implementation: If we could get Mobile Occlusion with a low CPU hit + Multiview we’d be onto a real winner here…
