Hi there, Some of you may already know me as I'm the author of Ultimate Terrains. Today I would like to introduce a new product I'm developing (for those who bought Ultimate Terrains, don't worry, I'm still developing it as well!). I realized that many people don't need a procedurally-generated-and-editable-in-real-time voxel terrain (especially because this is CPU/GPU/memory intensive), but still want to be able to create some caves, tunnels, cliffs and overhangs on their classical, standard, Unity terrain. This is why I decided to create this new product. With it, you will be able to: dig in your Unity terrain just like if it was a smooth voxel terrain. apply different textures on the cliffs, in the caves, etc. With it, you won't be able to: dig in real-time (even if that may change in the future). generate caves procedurally. Basically, when you dig in your terrain with this tool, it will automatically cut the terrain (making it transparent) at the right place and will generate a small chunk of voxels just where you need it. The resulting mesh is created thanks to Marching Cubes, using the new Job system and the Burst compiler. It is extremely fast, this is why in the future it will probably be possible to dig in real-time as well. Of course, it also automatically creates a collision mesh as well as proper triggers to automatically disable terrain collision for the right objects at the right time. No need to add any script on your objects. It is handled automatically. A video is better than one thousand words, so here it is: The video looks like it is laggy when I press play, but it isn't. BTW, I'm not sure how I should name this product... Could you answer the poll or give me better ideas?
