Unreal Engine 4.24 Preview

That’s the most horrible part about Unreal in my opinion. I always install GPULightmass, but they haven’t compiled it for 4.24 yet.

I believe support for VS 2017 was dropped on 4.22 or 4.23.

According to the documentation it was not (Setting Up Visual Studio for Unreal Engine | Unreal Engine Documentation), I also don’t remember any of the change logs mentioning anything about deprecating VS 2017. VS 2015 was just dropped a few versions ago.

Does anyone know why in the 4.24 preview the VR controller inputs are missing? Can’t make my previoulsy created blueprints to work properly anymore.

VS2019 is still far from really stable. They added support for it in UE4 but dropping support for VS2017 would just be unwise.

Still no flag/report button…

what i ve tried :
Check plugins and enable all chaos plugin
restart
try to make a blueprint from chaos solver class
add it to your map
fracture a cube added previously

play , it does not crash but i can’t enable gravity to check collisions and fracture

Hey @ClavosTech, I did some testing and you’re correct that a report option doesn’t exist for all users. I will figure out why this is the case and if it’s something we can enable. Appreciate the link to the report from 2018!

Motion controller keys have all now been set with a new flag where they can’t be directly referenced in blueprints. Instead you are expected to make actions for each of them and use those action events instead of directly referencing the keys.

This is because they are moving to OpenXR and that input modality is entirely based around rebindable “actions” where the exact keys / buttons being used are abstracted away from the development side.

@VictorLerp

No worries.

If enabling the Flag option for everyone is a big ask, maybe just allowing mods to delete posts in those threads will help. Anyway, I mentioned it because even just inadvertently hovering over malicious links in those threads could leave users exposed…

Trying to compile 4.24 P2 using Vs2019. Getting this “GenerateProjectFiles ERROR: Unable to find a valid installation of Visual Studio. Please check that you have Visual Studio 2017 or Visual Studio 2019 installed, and the MSBuild component is selected as part of your installation.” When running “generateprojectfiles.bat”.
The installation works. Has no trouble loading a sln file from a previous compile. The bat file is not set to the right location.

Should GTAO be working fine in 4.24P2? When I was testing it in 4.24P1 it worked, but now in 4.24P2 I can no longer get it to work.

@frostic try using the Weld Edges tool. This may fix your problem. Otherwise you will need to use a tool like Maya/Blender/etc to “stitch” or “weld” those open edges. (You might need to use the Normals Tool afterwards)

Preview 2 crashes when moving folders in the content browser, on Linux. This same folder causes issues when attempting to move it in 4.22.3 as well, when attempting to move it and fix redirectors it leaves “empty” folders there instead that can’t be moved or deleted, where if you look outside the editor in the file explorer you will see files(likely to be redirectors, but am not sure) left in those “empty” folders, but you aren’t able to see them within the editor. Not every folder does this, but many of them do, often ones from the marketplace, which is nonsense because you need a way to organize those files into your own project.

Not only was the issue not fixed from 4.22.3, but it’s actually worse in 4.24.0, it actually will crash the entire editor now if you attempt to move the folder…
You can follow two other topics of mine which are related to this one, here https://forums.unrealengine.com/deve…-related-files And here https://forums.unrealengine.com/deve…-still-in-them

Would really appreciate a backported fix for this into 4.22.3 as it is making things a nightmare to have this specific bug across 3 versions. To be honest I think this is a bug even as back as 4.18 and earlier…

Also make sure to check out the template folders in your install location under Templates for more info.

UPDATE!

We have just released Preview 3 for 4.24! Thank you for your continued help in testing the 4.24 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.

For a list of known issues affecting this latest preview, please follow the links provided on the original post in this thread.

TSoftObjectPtr seems to be losing references to assets when re-loading a project (Preview 2)

Also, TAssetPtr no longer gives any deprecation warnings and is a “valid” type. Should probably be removed by now…
