Unreal Engine 4.24 Preview

[batman2142]

I am on Preview-3 and cannot package a build.

I have my own ViewportClient inside a plugin and its giving a cooking error:

Failed to load '/Script/MyPlugin.MyViewportClient', falling back to 'GameViewportClient'

I can play the game in the editor and it works fine, but packaging is not working.

Instancing of runtime generated meshes now possible?

I found a new ProceduralMeshConversion.cpp in the UE 4.24 source, building a FMeshDescription from the UProceduralMeshComponent in the „BuildMeshDescription“ method.

So I guess now I could read synthetic environment data (e.g. 3DTiles) during runtime, build a procedural mesh out of the glTF mesh data and then convert the UProceduralMeshComponent to a MeshDescription, build a static mesh from that and then use this as the base for a lot of instanced static meshes?

If that’s the case can someone give me an idea how to create an UStaticMesh from the MeshDescription struct (that I get from the conversion from ProceduralMeshComponent)? I read into the code a bit but the mesh code without any prior knowledge on how it is handled in UE is not easy. I have the feeling that I’m missing something and that it should be simple to create a UStaticMesh from the MeshDescription.

What happened to the Anisotropic shader? I can’t find it on the roadmap for 4.24 but it was there not long ago.

Any ETA on when 4.24 should be getting OFFICIALLY released?

I have no inside knowledge but the way this has been going lately is they’ll go through some number of preview builds, usually 1 per week, and somewhere around preview 8 is the likely release build. So that might suggest that 4.24.0 would be released sometime in January, maybe late Jan or early Feb depending on how much the holidays slow things down.

Thanks !

It will be great to have an example workflow and test assets in the future especially in relation with the Shave and a Hair Cut purchase.

@Tim_Hobson

I’ll have documentation in place for the final release. At the moment, we’re not planning on releasing any assets, test ones or otherwise. We may add some in the future, but that is yet to be determined.

Right now, to get started with Hair, enable two plugins: Groom and Alembic Groom Importer.
Export your Groom from your DCC app and save it as an alembic file (.abc). This will give you a special Alembic Groom Importer window when you attempt to import it.
It’ll create a Groom asset in the Content Browser. You can open that to see some of the available settings.
Drag your Groom into the level and you can start changing some of the other settings like the default hair material.

I know this is very high-level instructions, but at launch, I’ll have an Overview, Quick Start, and Reference material in place to get people started using it!

[USER=“4894”] Hobson[/USER] I can import static hair no problem but I wonder if the documentation will include how to make it dynamic via Niagara? I’m also curious whether it’ll be possible in the future to drive the hair color by an underlying mesh or a map and not just one solid color? Thx!

Deterministic Actor-specific physics which network-replicate correctly for vehicles etc, when?

To apply physics, do the following:

• • Add a Niagara Particle System Component as a child of your Groom Asset

  • If it’s in the world, do this through the level details panel and select “add component”

  • If it’s in a BP, do this through the components window and make it a child of the Groom component

• Select the Niagara Particle System Component and next to the Niagara asset assignment box, you’ll want to select the Niagara Emitter called **GroomAssetSystem. **

  • If you don’t see it in the list, be sure that you’ve enable the view options to show Engine Content and Plugin Content and that you’ve enabled the Plugins for Niagara and Niagara Content as well as both Groom plugins.

This particular Niagara emitter comes with a bunch of properties that you can adjust to change how your hair behaves. Docs will be published with more details about all of this when 4.24 is released.

Thanks for the prompt and detailed answer !

Does anynoe try Almbic curve import UE？
I can’t find any parameters for dynamic fur

[Anafeyka]

Is it possible to dynamically change the hair count?

Are there any examples or information on how to edit the landscape at runtime instead of the editor? Everthing I’ve seen so far only shows the tools being used in the editor, but this:

Up until now Landscape data could be imported and/or edited from the Landscape Editor Mode only. This new feature opens the Landscape data to Blueprints.

implies that the landscape can be edited at runtime. Is this true? What steps are needed to make this work?

You will find the info at this recently added Epic video :

Unreal Engine Open World Preview and Landscape Tools | Unreal Dev Days 2019 | Unreal Engine

[3DMoss]

Thanks, I’ve watched that video, but all of the landscape tools appear to be editor only. I haven’t been able to get the landscape blueprint brushes to make any changes to the landscape at runtime. They just seem to be baked in to the layers when the game is played. At this point, I just would like to know if it is even possible.

People have been asking for a way to edit the landscape at runtime for a long time, and I thought we finally were given the ability to do so (without heavy source modifications), but it looks like this is just more editor tools, which is really dissappointing. Unless I’m missing something?

Runtime editing of landscapes is **not **supported with these new features, as the note mentioned, they are Editor-only.

The wording could have been clearer on the note that was posted with the preview, however, keep in mind that a lot of the notes there are still in an early draft phase and are subject to many revisions on the path to release. Apologies for the confusion and we’ll strive to be more clear with future releases.

I have a question about: Modeling Mode Sculpting Tools (Experimental). Sculpting Tools are a subset of the Modeling Tools Editor Mode. We know that this kind of tool is of particular interest to artists, so we wanted to give you some details! The feature is a simplified version of 3D sculpting found in DCC tools like Mudbox or ZBrush. The basic concept is the same: you click and drag on your mesh to push the vertices around…"

Will we be able to create a character and apply a skeleton to it within the viewport? Or perhaps , export the sculpture then re-import or save it as a skeletal mesh? That would be EPIC!

And this here!? “As an ongoing initiative, integrated PixelStreaming with UE4 Media Framework. This allows basic Pixel Streaming playback inside UE4.” Just awesome!

Any word on if we’ll see fixed raytraced shadows (as in without using the console command to turn off temporal accumulation) cos atm they’re horribly broken when something moves in the shadow…

If you make the ArchViz template, place a sphere and apply an unlit material, it shows up black - what’s up with that?

[HRound]

For whatever reason, when i got the option to install Version 4.24, I lost the ability to use Version 4.23. Does anyone have a solution that could work?

I don’t know why it’s not showing up in the launcher, but you should still be able to find your 4.23 installation, go to the Engine/Binaries/Win64 folder and run UE4Editor.exe.
