Unfortunately I can not update to version 4.8. Just EPICs need to update package to the newest versions of the engine, every time. In older versions it is not working.
I can advise the upgrade engine. Or if you really need version 4.8 send me an email alex044@gmail.com , I will send you the relevant FBX files, but then you’ll have to import them in the engine.
And on the version 4.10 update is ready
