*`--export-palette`: will save the included palette as png next to the source file. Use in combination with `--src-palette`.
*`--filter <filter>`: will filter out layers not mentioned in the expression. E.g. `1-2,4` will handle layer 1, 2 and 4. It is the same as `1,2,4`. The first layer is `0`. See the layers note below.
*`--force`: overwrite existing files
*`--input <file>`: allows to specify input files. You can specify more than one file
Some formats also have layer support. Our layers are maybe not the layers you know from your favorite editor. Each layer can currently only have one object or volume in it. To get the proper layer ids (starting from 0) for your voxel file, you should load it once in [voxedit](../voxedit/Index.md) and check the layer panel.
Especially magicavoxel supports more objects in one layer. This might be confusing to get the right numbers for `voxconvert`. See [this issue](https://github.com/mgerhardy/engine/issues/68) for a few more details.
