Thanks.
The core of Pixzels is a dedicated voxel engine with some specific tricks to accomplish a real pixel art feeling. The model is not real Voxels but similar tech. Atm the export options are 2d pixelart (power of 2) sprites usable for any game engine. As a pixelartist if I export as 3d obj it would lose all the pixelart feeling that I was looking for this tool. Working still on it, I might include 3d export on the future updates,... Not sure yet. Many Thanks Fluffy Sheferd. :)
