Does Chaos Clothing Asset's work with Mac Version of UE 5.4?

JasonNeptune · May 8, 2024, 2:04pm

Hi

I just installed the new version of UE. I have installed all plugins for Chaos Clothing but there is not way to create a clothing asset. Is this a Mac thing? Or is there something wrong with my plug ins? Do I need to update them as well?

Every bit of documentation says you install plugs> Restart> Right click content draw> Go to physics tab> Click Cloth Asset. Apparently it’s super simple and easy and a huge feature of the new engine but all I get is this in my physics menu… No Cloth Asset creation available.

Has any body found a work around or some other way to create a cloth asset from a USD file from Marvellous designer. Or can I some how change my FBX version of the clothing into a cloth simulation another way in UE 5.4? Or do I just keep rocking my characters birthday suit?

Hi. I’m writing to say “me too” I don’t yet have a solution.

I can confirm this behaviour in two separate macOS laptops.
I tested opening the files in this tutorial to see if UE would recognize them but nodes in the data flow are immediately disabled and an error is thrown in console.

By the look of it it seems FChaosClothAssetUSDImportNode is not available even when the Cloth plugins are loaded.

Tested on 5.4.1, both built form scratch and downloaded from Epic launcher.

I think I may have a lead into this problem. The plugins source code resides under /Engine/Plugins/ChaosCloth*.

ChaosClothAsset.uplugin does not have PlatformAllowList,
ChaosClothAssetEditor.uplugin does have PlatformAllowList but Win64 only

I will test if adding “Mac” as platform will compile and work.

Any solutions you stumbled across?

PabloAtZozo · May 29, 2024, 6:37am

@JasonNeptune
Yes, what I explained in my previous message worked. You have to recompile UnrealEditor (branch: release 5.4.1).
After that the data flow nodes and ClothAsset open and worked well.

However, after I added a character compiled blueprint to the map and packaged for visionOS the actual cloth is not loaded. The app did load and work well (scene loads, character model loads, model animation plays correctly). But the cloth is not loaded.
This is the error I get in case someone wants to go further:

I have not looked further into it because I’m not currently working on this project.

S3w0lf · July 7, 2024, 8:26pm

and how you do this ? “recompiling” ?

JasonNeptune · July 16, 2024, 5:24am

No idea I’ve just skipped clothing at the moment nothing I’ve tried will work so just rolling with armor cloths ATM. You would need to recode the Engine Files which I’m not keen on playing around with without some proper instruction. Hopefully next update will fix the bug.

Boojs · September 5, 2024, 4:54am

I believe you should just rebuild pointing to your project.

Engine/Build/BatchFiles/<Platform>/Build.sh <ProjectName> <Environment> <Platform> -project=/path/to/project/project.uproject

ie:
Engine/Build/BatchFiles/Linux/Build.sh MyProject Development Linux -project=/path/to/project/project.uproject
