i was looking at some other free editors the other day, to see if i could find some other free editor to replace voxelshop, but none of them said whether they did or did not support multiple matrixes… so… i’m not sure, as i haven’t actually used anything other than Magicavoxel, VoxelShop, and Qubicle…
yes, you can use blender, there’s even a[ stonehearth add-on] (Stonehearth Add-On for Blender (Animation)) for it. though i’m not sure if it still works…
i believe there is some info in an entities .json that connects it to the anims… but not 100% certain on that
to be honest, i have not a clue how anims work, i’ve never needed them for a mod yet…
@Hyrule_Symbol (hope you don’t mind me paging you Hyrule) knows a lot more about the animation side of modding than i do, so maybe he could help answer your questions?
looking at my reply, i realize i’m actually the worst person to be answering these questions, as i barely know any of the answers to your them…
