Reopening here since I realized I wrote the issue in the wrong place.

Hello, thanks for providing this plugin. After testing for a while, I think the issue is with the plugin, but if it is not I would be glad to know how this is being used elsewhere. So I started to use this plugin 4 days ago, I have been working to make a model procedurally. At the end of generation the function save the Model as a test.off file, call the plugin GenerateSkeletalMesh and return the result, which is then loaded in an Actor via blueprints. The blueprint run at Event Begin Play. The output teste.off file is always correct, you can load it in any tool to check that it is the same everytime, but the output from GenerateSkeletalMesh randomly changes. The function calculates the normals, tangents, uvs, set colors to (0,0,0) and flipnormals to false, set every vertex to the 0 bone. My function outputs a cylinder/capsule model. Sometimes the model is rendered correctly, but many times it is rendered in very weird patterns. On my side the result output is always the same, but in the engine the end result changes from play to play in bizarre ways. You can see the code and the teste.off file here: I also ported the plugin to UE5 (but the same issues happens in Ue4.27) Can visualize the teste.off file here:https://3dviewer.net/ https://github.com/Fransferdy/creaturecreator

Hello,

Are you able to provide an example of how you have used this class to generate the skeletal mesh? I've been trying to implement this into my game but I keep getting crashes during the PostLoad function. I think it might be the way I'm importing the mesh but I'm not too sure.

The rationale for this change is that this plugin may be used by many modules, and it's really bad include this file many time. Use a shared plugin is just convenient.

Hi, I use your plugin to create skeletal mesh and apply it to my character by using SetSkeletalMesh(), but, when walk around or travel to a different map, it randomly crash on my game, how to fix it . BTW, the crash only happen on packages, not PIE or standalone mode.

Looks like animation is broken. This is basically the example plus the 2 lines copying the animation from the original mesh. The skeletal mesh works fine is it's just static without the animation.

The video attached is using the skeletalmesh and animation from the content examples. I've tried with other skeletal meshes and same issue.

This is tested with 4.27.2

void ADuplicateSkeletalMesh::Duplicate()
{
	TArray<FMeshSurface> OutSurfaces;                  
	TArray<int32> OutSurfacesVertexOffsets;            
	TArray<int32> OutSurfacesIndexOffsets;             
	TArray<UMaterialInterface*> OutSurfacesMaterial;   
	
	USkeletalMeshComponent* SkeletalMeshComp = SkeletalMeshActor->GetSkeletalMeshComponent();
	FRuntimeSkeletalMeshGenerator::DecomposeSkeletalMesh(
		SkeletalMeshComp->SkeletalMesh,
		OutSurfaces,
		OutSurfacesVertexOffsets,
		OutSurfacesIndexOffsets,
		OutSurfacesMaterial);

	USkeletalMeshComponent* comp = FRuntimeSkeletalMeshGenerator::GenerateSkeletalMeshComponent(
		this,
		SkeletalMeshComp->SkeletalMesh->Skeleton,
		OutSurfaces,
		OutSurfacesMaterial);

	comp->AnimationData = SkeletalMeshComp->AnimationData;
	comp->SetAnimationMode(EAnimationMode::AnimationSingleNode);
}

Skeletalmesh on the left is the original and the right is the duplicated one.
