What is a VOXEL??? Voxel is short for volume pixel, the smallest distinguishable box-shaped part of a three-dimensional image. Voxel Sculpt empowers users the ability to create unique and custom worlds one voxel at a time. By adding or subtracting voxels, users can create bridges, tunnels, caves, floating platforms, buildings and assets using soft or hard-edged voxels, any size, and with any texture for limitless possibilities.
