Hello!  I picked up this asset pack because I thought it would be useful for a scene I was making, but it seems like all the items are packed in Unity asset format.  Would it be possible to get a version with the files in some other format like GLTF or FBX or even .blend?

Sorry for the delay, I have been away. 
Could you send me an email at Johannesnienaber@gmail.com? What exactly would you like me to do? Convert all the files to fbx? They should be FBX already.
