Cubicle is a nice voxel editor, but I prefer the 3D paint program feel of Paint 3D — http://www.paint3d.net — and want to have a go at the free open source Magicavoxel editor — http://voxel.codeplex.com
Yes of course ;)
But if the direct import of OBJ is perfect, I am not sure that the Subdivide can make something without some simplify or tricky manipulation
because it's real "Voxels" ! So some cubes or more some facetts! ;)
I must find some workaround first! :)
As it's facets Boolean Union will be the solution - but not sure that wotks for a such number of facetts in a reasonable time!
A Possible workaround :)
