Hi! Thanks for joining, It's not short, never too late :)
There's ony one Voxel Art creation software that's worth it, it's Magicavoxel. It has a lot of export option, the tools are intuitive and greatly designed, it's fast, efficient, the render is beutiful, and it has a complete set of functionalities (scripting, outiner, layers, multi-volume support, etc...)
And It's completely free. :)
I'll make a sticky note with some good resources to have today, thanks for the suggestion.
