dont' need this, just delete it. Mirroring does not look good because of the wrong direction of the shadow, but better than nothing
for nodes like furnace. For a proper solution, generate block images from textures.
### Generate Block Images from Textures
This one was intended. With the [MTSEdit Minetest Mod](https://gitlab.com/bztsrc/mtsedit/tree/master/mt-mod) you can save
`blockimgs.csv` with the node's texture data. To import that data, use
```
./mtsedit -t ~/.minetest/worlds/MyWorld/blockimgs.csv
```
This will generate the block images as well as the slab and stair images into the CURRENT WORKING directory. You can then select
what you need and copy those to the `data` directory on your system.
