Enhanced Fireplace from Sweet Home 3D (as allowed by the licence LAL which I understand to be equivalent to CC-BY-SA).

A walkthrough with this lightmapped fireplace can be seen here:

This fireplace is enhanced by:
- bevels
- PBR textures (that can easily be replaced by other ones)
- Seams for direct UV unwrap
- Lightmap

Rendering with lightmap may be useful for walkthrough animation of interior scene.

The lightmap has to be changed according to your lighting and environnement but may be suppressed.
