I didn’t spend a lot of time on this - around 2 and a half days. This morning I saw a video for a terrain editor that really kicked ass, so I copied some of the ideas they showed in the video. Here’s a little video…
Their product is like $150, admittedly it does quite a bit more than this. That said, would people be willing to buy something like this, and would anyone be interested in making this into a proper asset store product (doing support and improving it, responding to customers, etc)?
The thing isn’t very compex, but the results are quite good.
