MagicaVoxel and R3F together

I won't describe how MagicaVoxel works and how to use it.
Mainly because I have only used it once and only to perform the export tests described here.
My goal was to see how to go from MagicaVoxel to Rocket3F.

Rocket3F can import :

OBJ
DAE
FBX
DXF.

MagicaVoxel can export :

OBJ
PLY
MC (PLY format)
xraw
slab
qb
vox
iso
2d
slice
point (PLY format)
cube (PLY format)

So it is obvious that one has to use the OBJ format, which is the only one they share.
Helas no...

If your goal is to import your voxel model in Rocket3F, OBJ is not your best choice.
The OBJ export triangulation from MagicaVoxel is far from ideal for further modeling in R3F (try it and you will see by yourself...).
Ideally we want quads.
And as voxels are cubes, it should be easy for MagicaVoxel to end up with quads.

Let's see the other export options we have...
Except from PLY I must admit I have never seen these other formats.
Let's try them all.
Doing so you will discover that MC, point, and cube do also have a PLY extension.
So chances are they can be good candidates too.

What's the difference between these formats ?
As I told you the OBJ is not a good candidate.
What about the different possible PLY ?

Except for the 'Point" export format which only contains vertices, all of the other PLY are good to go !
They will all produce a regular polygonization grid distribution (ala "Rubik's cube") just as expected.

Note that you still end up with triangles (there are diagonals separating our quads).
But you will be able to easily select them and get rid of them in R3F (select similar), making things easier afterward to select rings and loops for further modeling.

Our 3 kind of PLY are :
