IsoVoxel

MagicaVoxel is an 8-bit voxel editor and path tracing renderer that comes with an extensive feature set and enables users design models for various projects.
IsoVoxel is an open-source utility that can process VOX files created with MagicaVoxel in order to generate isometric pixel art. Even though it is a command-line program, it is very easy to use.

Generate isometric pixel art from MagicaVoxel files

When a VOX file is processed, the application will create a subfolder named after the model where all the generated images are stored. A total of 44 images are created, showing the model from various perspectives.
The bounds of the model can be customized, and they do not have to match the dimensions given in MagicaVoxel; this feature makes it possible to render multiple models at the same position in the images.

Don’t be discouraged by the lack of a GUI, as this program is quite intuitive

If you don’t want to use the command console, there is a simpler way to do things: just drag a MagicaVoxel VOX file and drop it onto the executable; it will be processed instantly using the default parameters, and the renders will be stored in a new folder.
Of course, you will have to use the command-line if you want to have more control over the operation. Aside from setting the X, Y and Z bounds, you can also select the preferred outline mode. IsoVoxel can use three types of outlines or none at all.

Relatively straightforward command-line program for creating isometric pixel art

In the end, IsoVoxel would certainly benefit from a graphical user interface, as modifying advanced processing settings is still quite difficult, but, on the whole, the application is fairly intuitive.
It is a great tool for users who work with MagicaVoxel and want to create isometric pixel art from their models, and it is perfect for those who don’t mind using the command console.
