Simple voxel sprite creator made with Godot Engine (Link in description). 

As you can see in the video, you can set the thickness independently, so it looks less flat. It can be useful in some scenarios. Also, you could modify it to accept a bump map, and manipulate the z scale of each voxel independently. I don't know how to create a good bump map, so I haven't been able to test and implement it yet, but it should be one additional line in the shader, if you have the map. Feel free to experiment with the code!

@@afterfivegamedev - Cool, was just curious. It's a neat idea. I saw "voxel doom" and that was pretty interesting looking.

@@Uhfgood Well, mine is not as advanced, as Cheello made all the models by hand, while I'm creating them automatically from sprite :)
