Slightly scratched heater.
This is low-poly model of heater.
Model including high quality textures. Texture size 4096x4096.
PBR: base color, roughness, metallic, normal map, AO (also added a folder with textures for Unreal engine).
Tested in Marmoset Toolbag 4. When rendering the model, I did not use the AO texture, because it darkens quite a lot inside.
