[Tutorial] Flow direction based in height map

Someone in the forums asked the question about moving lava based on their mountain slope, such that on the left side of the mountain it flowed down to the left, and the right side down to the right, etc etc. Took a little while to work out the solution for one key element but I finally got a working result. Hopefully it provides some inspiration for others and maybe someone has an easier solution… but for now, here’s mine :slight_smile:

Quick update video to show it in more detail and provide some tips as well to make it easier and improve quality.
