Stride Voxelscape
An open source voxel engine using C# and the Xenko game engine. Still in the early stages of development and no longer being actively worked on. Released under the MIT License.
This was pulled from LyingDwarf's BitBucket long ago and I attempted to convert to Stride with little success. I am uploading it anyway since the original repo seems to have sadly gone away. https://bitbucket.org/LyingDwarf/xenko-voxelscape/src/master/
