Recreating a Unity Material in Blender

I created a charakter at https://heroforge.com and bought it as a Unity-Asset for 3D Tabletop. (The Download file has the .unity3d Extension, whats correct name for this format, Assetbundle?

Now i want to import this into blender to do some custom rendering. As i a fairly noob in 3D modeling i followed the blender parts of this Guide https://www.reddit.com/r/talespire/comments/obx9tm/a_stepbystep_tutorial_to_get_your_hero_forge/ .

Textures extraced from the UnityPackage are:(texture_diffuse.png, texture_emissive.png, texture_metal.png, texture_normal.png, texture_occlusion.png)

The Diffuse Texture is mentioned in the guide and is reponsible for basic coloring, the others are not mentioned but should be relevant for light-reflection and surface details right?

This worked partly, what seems missing are some 'effects': What works: Mesh itself, basic coloring and after experimenting and following some tutorials it seems that i got the normal map working.

Rendering in Tabletop Simulator (digital 3D Models from heroforge are intended to used with this):

Rendering with Blender:

So how do apply the other render effects and other things described in the Unity Package (it contains some other properties for the material and some kind of armature i think) to recreate the rendering from heroforge?
