Chaos Cloth Panel Consistently Crashing at Skin Weight Transfer

Development Asset Creation

There is always the major potential I am doing something wrong, either in the MD cloth exporting itself, or the character’s skin weights, however beside that I have followed the Cloth Panel Tutorial exactly.

I cannot find anything since it’s release that point to this being common. and I know this is experimental…

Any direction towards making this work would be grandly appreciated
thank you!!!

I am running into the exact same issue.

I was initially using a mesh with many material slots (13) and simplified them to be 3 slots and did not observe the crashing anymore. @FaradayPrime Perhaps you could try reducing the number of material slots?

Have you fixed it, sir?

I’ll just throw my hat in and say I’m having similar issues. I’m getting crashes that say something like:

Assertion failed: FaceVertex == TVec3(INDEX_NONE)

If it doesn’t crash, I’ll get a message like: TransferSkinWeights: Transfer Weights Failed.

I’m not sure if its the skinned mesh character I’m trying to use, or the render mesh or sim mesh (all are just using one material). It seems to crash more consistently if I add the ClothAssetTerminal node into my graph.

Definitely seems to be in the experimental phase, maybe Epic could provide more guidance on the types of meshes that will / will not work with the Panel Cloth pipeline.

I tried two methods to fix it. One is to add material at solt in character. One is deleted all bone except deformed bone.

It’s completely unpredictable for which cloth it will crash and which is ok.
I successfully added quite complicated female clothing but failed with a simpler T-shirt.
I had the same error D_Chap posted, tried to use merge by distance in Blender tool, but even I reached to loose quality, the crash still here.
I don’t think it depends on complexity/number of faces b/c my successful cloth was the most complex. Hopefully it will be fixed in 5.4 (or at least UE should show some informative error instead of crash).

I solved this problem by fixing the fbx file. In my case, the error occurred after exporting fbx from zbrush. I’m using 3ds max, but even re-exporting the model from zbrush doesn’t help.
I fixed this by selecting all the polygons in edit poly mode, then detach it. After this, the smoothing groups are lost, but most likely this is not a problem.
I haven’t tested it, but I advise you to export the mesh in obj format and only finally export it to fbx via 3ds max or better maya
