_Anim suffix added when it shouldn't when importing animations

According to this code in
UnrealEngine/Engine/Plugins/Interchange/Runtime/Source/Pipelines/Private/InterchangeGenericAssetsPipeline.cpp


	if (bUseSourceNameForAsset || !OverrideAssetName.IsEmpty())
	{
		//StaticMesh
		if (MeshesImportedNodeCount == 1 && StaticMeshNodeUids.Num() > 0)
		{
			UInterchangeStaticMeshFactoryNode* StaticMeshNode = Cast<UInterchangeStaticMeshFactoryNode>(InBaseNodeContainer->GetFactoryNode(StaticMeshNodeUids[0]));
			const FString DisplayLabelName = OverrideAssetName.IsEmpty() ? FPaths::GetBaseFilename(InSourceDatas[0]->GetFilename()) : OverrideAssetName;
			StaticMeshNode->SetDisplayLabel(DisplayLabelName);
		}

		//Animation, simply look if we import only 1 animation before applying the option to animation
		if (AnimSequenceNodeUids.Num() == 1)
		{
			UInterchangeAnimSequenceFactoryNode* AnimSequenceNode = Cast<UInterchangeAnimSequenceFactoryNode>(InBaseNodeContainer->GetFactoryNode(AnimSequenceNodeUids[0]));
			const FString DisplayLabelName = (OverrideAssetName.IsEmpty() ? FPaths::GetBaseFilename(InSourceDatas[0]->GetFilename()) : OverrideAssetName) + TEXT("_Anim");
			AnimSequenceNode->SetDisplayLabel(DisplayLabelName);
		}
	}

If I have Use Source Name for Asset and leave the Asset Name empty ( see bottom part of code) it should import the asset with the name as is. However the _Anim suffix is added.

If I turn off Use Source Name for Asset and leave Asset Name empty the animation sequence is imported without the suffix.

But the code suggest it should be the other way around?

What gives?

Hello @Sidar ,

The mentioned code block runs, if either “bUseSourceNameForAsset == true” or there is an OverrideAssetName set.

So if you set bUseSourceNameForAsset to false and leave the Asset Name empty then the code block won’t run and hence the suffix won’t be added.

While if you have the bUseSourceNameForAsset as true, the code block will run, and the animation will be named after the SourceName with the suffix added.

As far as I can tell the behavior follows the code.

The suffix, I believe, is added, because the system is expecting more assets to be imported (SkeletalMesh, etc) and thus it is preparing to avoid Name conflicts.

Hope this helps.

Much obliged,
