I thought I saw it mentioned in a GDC talk that Epic would release the streamer they built for the ILM Xlabs raytrace demo for streaming to the Ipad to the general public in 4.20. Is this still in the plan? I don’t see it on the list.
Ok, that is encouraging, thanks!
And no I have not encountered any freezing in 4.19.
We have just released Preview 5 for 4.20! Thank you for your continued help in testing the 4.20 build before its official release. As a reminder, the Preview builds are for testing only, and should not be used for the active development of your project.

Hi, i’m newbie in ue4 and have no Mixed Reality Capture Framework C++ Classes in my content browser (plugin enabled) in UE4.20 Preview 4 and Preview 5 for MacOS. How can i fix this?
Is there a way to disable the display of the hdr panorama background in the Niagara editor ? I see there is a keybinding option, but it’s doesn’t do anything. Please add option to disable this and set the background color.
Finally, why did this take so long!?
It must be about the new action rpg example?
No, you now have to use potions inside the editor to access certain features. Like the potion of truesight that allows you to open the blueprint finder.
Is that one real or some kind of easter egg? Looking it up on the issue tracker comes up as unknown issue… Would be interested to see what it says.
Epic, can you guys make UE-60943 public?
I was joking obviously, @Zeblote was right, it’s more than likely that it relates to the upcoming action rpg content example.
Apologies if this has been discussed already somewhere, but has anyone looked into the new “Volume Texture” asset type? It seems like it should be pretty straightforward to use in that it takes in slices from a packed 2D texture, but so far all I’ve been able to do is make the editor crash immediately.
I’m also not sure how/when to actually sample from the 3D texture. I’d assume that it works with volumetric fog, and maybe some kind of ray marching tutorial, but other than that I’m not sure.
with the new release 4.20 preview 5 I can no longer create new Unreal Studio Product View projects because when I start my project, it tells me that it can not access a plugin
“staticMeshEditorExtension failed to load …”
in the attached two messages that appear to me. can I bypass the problem?
Giorgio (GiDiO) D.E.
Is it allready on steam or not ?! Aswell people recomend me an website with wheels size calculator by the make of the car please?! i found that one Wheel & Tire Size Calculator – Tire Reviews witch is really great but to comapre?!
Following on from fix of UE-60969 (relative include path issue in build rules), I’m still getting failed plugin builds on preview 5.
I now get compilation failures with inability to locate #includes from engine module dependencies. If I have a module dependency specified and #include “File-name-only.h” for a header somewhere in the other module’s public folder, it fails. Seems that public include paths aren’t being propagated correctly.
Same problem… relative include fails… i have preview 3 though, so i’ll try to update on the launcher if it’s available there
Edit: Just tested with Preview5, it did throw me the warnings but it did compile, so maybe i’ll have to reset and re-check
Found a crash with HISM (Hierarchical Instanced Static Mesh) components used in native classes and expanded on Blueprints.
Added description and test files in answerhub. Filed a bug report as well.
Update: Found a workaround. Use only C++.
It seems the problem (and also a visual one in my other post) is related only to Blueprints. If the class using HISMCs is purely native, no crashes occur. But even the class’s children have to be native. Any Blueprint intervention and it crashes.
HISM components set to static mobility have lightmap sampling errors in edit mode after the Lightmass build. But on Play/Simulate they look like expected. Attached image demonstrates the issue.
I’ve reproduced it by adding an EmptyActor to the level with two HISM components and some instances added to them. Set the HISM components to Static and built the light.
I’ve also attached my system specs.
Edit: it seems to only happen on HISMCs inside Blueprints. Even if it is a blueprint that is a child of a native class and the native class instantiated the HISMC. But it’s not happening with purely native instantiated HISMCs.
I’m finding it very weird that no one seems to be bringing up anything about the HISM component. I’ve been having problems with it on 4.20 since I started testing it on preview 2. But only this week I’ve had the time to set up reproduction steps.
I’m really thrilled about this release. Been loving to work with Layered Materials, but in 4.19 you can’t reorder them and sometimes it takes more than 5 minutes to re-setup materials above a new inserted one that should go in the middle of the others. It’ll be very sad to have to stick to 4.19 because of HISM bugs. And I’m using them a lot. It’s a huge environment with several repeated pieces. Not to mention the new DoF that’s awesome for showing the work to your customer.
I’m also using HISMCs a lot, and actually, there’s a very horrible bug with HISMCs in both 4.19 and 4.20:
This is how it looks like when you call AddInstance in 4.18:
And this is 4.19 and 4.20:
So adding instances on runtime is completely broken visually if you have any wind in your level, the wind seems to get reset for all existing instances when new ones are added in 4.19 and 4.20.
This breaks my game unfortunately, so I very much hope it get’s fixed soon.
I’ve posted about it on the AH too: Very bad regression with AddInstance for HISMC in 4.19, wind gets reset for all existing instances - UE4 AnswerHub
How does the wind system work in Unreal? Is it animated by a time variable?
