Wow, I was high sceptical that you would be able to scale this up past the short view distance. But not only have you managed to get a good view distance, but you also added in a nice animation system. Congrats to you! This is coming from someone who has spent years designing their own voxel platform. Please get this out to users to let them start building things, you will be amazed at what they can create.
