This mod replaces the permanent torch sconce mesh with a new, reimagined design. Both "burning" and "extinguished" meshes are covered. The new meshes are higher poly than vanilla and come with unique 2K textures. 

The Embers XD version (2) makes use of the much nicer Embers XD fire effects.
The Smoking Torches and Candles version (3) includes the smoke effect from STAC.
The Embers XD + STAC (4) version includes both the better fire effects from Embers XD as well as the smoke effect from STAC.
The Inferno - Fire Effects Redux (5) makes use of the Inferno fire effects.
The Inferno - Fire Effects Redux + STAC (6) version includes both the better fire effects from Inferno as well as the smoke effect from STAC.
Optional 1K textures are provided in the Optional Files section for those who want to save on some VRAM.

Special thanks to Mindflux for giving me permission to use their assets for the Embers XD version of this mod. The Embers XD version is the one featured in the screenshots.

Compatibility:
This mod replaces only the mesh files, no plugin/ESP included. The included textures are unique and will not conflict with any vanilla textures.

Installation:
Use your preferred mod manager to install as per normal.
Overwrite when prompted / give my mod priority.

Extended Description (for those curious about my method):
This is my first attempt at creating a Skyrim asset completely from scratch. I'm pretty happy with how it turned out, but I am sure it can be improved once I gain more experience. I do believe my mesh can benefit from having a material generated for it, so I can use one texture and less tri-shapes to optimize the mesh, but this is a skill set I am yet to obtain. I welcome any advise and constructive criticism, I still have much to learn.  

I modeled the sconce in Blender and also set out the texture UV's with Blender as well. I then exported the mesh to .nif format and used NifSkope to assign textures as well as mesh and lighting properties. I also used NifSkope to combine my mesh with the cloth and flame effects from the vanilla mesh as well as to align all the elements to correspond with the vanilla mesh positioning. Mesh conversion between LE and SE was done with SSE NIF Optimizer.
Even though this mesh is much higher poly than the vanilla one, I believe the new poly count to be reasonable for a modern game asset. I tried to use as little geometry as possible without sacrificing to much quality.
  
Texture wise, I believe 2K to be a sufficient texture resolution for an item of this size, 4K does not seem to add much visually, but does cost a fair bit more VRAM. 1K is a noticeable downgrade, but I decided to include it as an option for those who are restricted by VRAM. The metal textures were sourced from the Poliigon website and then downscaled and converted for compatibility with Skyrim using Cathedral Assets Optimizer. The wood texture is simply a renamed vanilla Skyrim SE texture, the texture UV of the wooden part of the mesh was adjusted to make the vanilla texture seem higher resolution in order to fit better with the rest of the textures. I chose to do this as I was unable to obtain a suitable free texture to use for the wooden part of the mesh.

Screenshot Disclaimer:
I ended up having to adjust the wooden texture after I completed taking screenshots and making the thumbnail. Thus the actual in game asset now differs slightly from the screenshots on this page. The wood grain in game appears finer, but the color matches exactly. The difference is so slight though, that I did not feel it warrants the required time and effort to re-do the screenshots and thumbnail. I just felt I had to be clear and up front regarding this matter.
