I have some old projects for a voxel art application called Sproxel, and I wanted to get them into Magicavoxel because the Sproxel editor is pretty bad and Magicavoxel has nice rendering.
Sproxel is old and seems to be discontinued (http://sproxel.blogspot.co.nz/
) but me, and possibly others, would definitely benefit from the ability to import their .csv files.
It's a simple .csv, an example can be found here:
The example shows 3 white voxels above 1 red voxel, in the corner of a 4x4x4 grid, which should be enough information to be understandable :)
