PBR material, with diffuse, metal, roughness, normal, emission and displacement maps in 4096px.

Normal map comes in 2 versions, for a high poly version and for a low poly version of the model, if you have subdivided it. The hi-poly normal map only contains bump information.
Low-Poly but it's subdivisible and has creased edges to keep the shape when subdividing.
Might require some modifications in the node tree to make it work in-game depending on the type of node setup you are going to use in your engine.
There's an emission shader mixed through a Mix-Shader node.
The window to the furnace has a transmission shader for the blurry glass effect instead of a transparency shader, which would just be semi-transparent.
The diffuse texture has an alpha channel, which is used as a transparency map, you can use a mix-shader node to combine it with a Transparent BSDF node for a lower quality result that would be easier on the rendering.
