3rd party assets

I recently bought a third party asset from the Vendors store.

They create low poly Unity and Unreal characters and are generally well regarded.

I have striggled to get it working as a 3rd person controller character.

What they have said

‘I have had a chat with our unreal team and the issue is with using the UE5 mannequin. We currently only support the UE4 mannequin on our characters. The UE4 mannequin works perfectly in UE5.
In our unreal projects we include the UE4 mannequin blueprint which can be used in your project and assign any of our characters,
​You can also just drag and drop our character fbx into your unreal project and assign them to the UE4 skeleton and blueprint and they will work from there.’

I have tried quite a few things to get it working, and failed.

Would love to hear from anyone who has got this sort of thing working, so I can get an idea of what Im doing wrong.

Didn’t want to publically name the vendor as I am still hoping they will support etc..
