If you have used Minecraft NBT IDs in the input file, then remapping is unnecessary.
### Converting to VOX
Normally convertion creates only MTS files. But to support bidirectional workflows, MTSEdit can write VOX files too using `-V`.
```
./mtsedit -V structure.mts structure.vox
```
Note that VOX files will loose a lot of schematic's details (node names, rotation info, probabilities, force placement etc.), but
at least you will be able load the structure in Goxel and Magicavoxel. When saved, you can convert VOX (or GOX) files back to MTS:
```
./mtsedit structure.vox structure.mts
```
### Generate Preview

Limitations: rotation info are not imported at all.

the same limitations apply. They are not perticularly good for storing schematics, as nodes has to be matched by color some nodes
might be incorrectly identified.
To aid workflow in both ways, as an exception MTSEdit can convert to VOX files too. This is the only format that's written which
is not MTS.
Limitations: this format can't store nodes, nor rotation info, only colorized voxels. This is a voxel image format, not a true
schematic format.
