Issues packaging unreal 4.15 personal license and building from source

This was a problem with the first 4.15 build of NeoFur, try upgrading to the latest build (currently 2.1.404). Unfortunately, I think the NeoFur source code is much older than 2.1.404, so you may have to use the compiled build for the time being.

Hello Sean,

This is a bit old but I am running into the same problem. However, using the precompiled version is not an option for me. Any chance that you can point me to the fix for this?

Best regards,

I can provide you with a fix; I fixed this in my source build, but please note while it seems to work perfectly, it might be different than what Neoglyphic did.

It turns out in 4.15, Epic has a new requirement for components that render in the editor. The editor needs to query the used materials via a new function (GetUsedMaterials), and because this isn't implemented in older versions of NeoFur, it crashes. So what I did was override that function and add all used materials for a fur component to it, and it works great. Here is what I did:

Add this to NeoFurComponent.h:

virtual void GetUsedMaterials(TArray<UMaterialInterface*>& OutMaterials, bool bGetDebugMaterials = false) const override;

Add this to NeoFurComponent.cpp:

void UNeoFurComponent::GetUsedMaterials(TArray<UMaterialInterface*>& OutMaterials, bool bGetDebugMaterials) const
{
    if(Material)  
    {    
        OutMaterials.Add(Material);  
    }

    if(FurAsset)  
    {      
        for(FSkeletalMaterial& GrowthMeshMaterial : FurAsset->SkeletalMesh->Materials)      
        {        
            OutMaterials.Add(GrowthMeshMaterial.MaterialInterface);      
        }  
    }
}

I only handle character skeletal meshes since that's what I need, if you use NeoFur on static meshes you can add another loop that gets the static mesh materials. And also, I assume there is always a mesh with materials, so it might crash if that's not true.

Hope this helps.

Hey Sean,

Thanks, this is an acceptable workaround for now until the NeoFur source code is updated.

Thank you, that did it!

I really like the way that you have expressed yourself. There is a lot to be admired from this post. You might want to click onThe Union Mark Wahlberg Green Jacket
