Did you know you can use easily make your own voxel art in Blender?
In this Blender tutorial I will show you how to use Blender to use the remesh modifier to make your very own voxel art.
Blocks
The remesh modifier is used to generate new mesh topology
If I select the first object and add a remesh modifier with the blocks option, you will see that the object’s mesh has changed to blocks without any smoothing
The octree depth refers to the resolution of the output with low values generating larger faces and higher values generating a denser output
The scale affects the output resolution with lower values decreasing the resolution
The remove disconnected option filters out small disconnected pieces
Threshold controls how small a disconnected component must be to be removed
Smooth shading means that the output will have smooth shading rather than flat shading
Smooth
The smooth option for the remesh modifier is used to produce a smooth surface
I have the same options that I did for the blocks option
Sharp
The sharp option provides for a smooth surface while maintaining sharp edges and corners
This option provides an additional field – sharpness – with higher values producing edges similar to the input and lower values filtering out noise
Voxels
The voxel option generates a manifold mesh while trying to maintain the mesh’s original volume
The voxel size is used to evaluate the voxel’s volume with lower values preserving finer details
Adaptivity simplifies the geometry by triangulating the faces
Smooth shading outputs faces with smooth shading instead of flat shading
Practical Example
I modelled a simple tree using a cylinder and some ico spheres
If I select the tree and add a remesh modifier with the blocks option, I can see the beginning of a voxel style tree
As I increase the octree depth, I can now see more of the tree
