I created stamps for free to be used with the Stamp Tool: https://forum.unity.com/threads/free-terrain-stamps-github.661399/ Problem is that there's no 3d preview available (unless you move over to the editor after you clicked a brush) and the brush name can only be seen when you use a tool tip. It's very hard to find out which brush is being used. The shape can eventually be made out from these small icons, not so the details like erosion, height, terracing, etc. Example of the problem: That's only 20 stamps. I intend to post even more stamps for free. I guess even if there were a 3d preview, it could become too much with a 100+ stamps. Maybe categories could help? After all the built-in paint brush is quite something different compared to the terrain brush. With the paint brush you sculpt. With the terrain brush you have full terrains. As a start: Is it possible to create a 3d brush and show it inside the inspector? Or does anyone have a better suggestion?
