I got a problem with the terrain. The title says it all, no matter what brush i select it wont change the actual brush within the editor. Changing the parameters of the selected brush does not change anything either. This goes for changing the actual terrain, painting grass and even textures. Only the first brush keeps being selected with default settings, and it will not change. I have looked trough the Unity answers and forums and found 2 answers, both came down to this: Re-install Unity. I don't buy this, because i had this problem before and for some magical reason the problem disappeared 2 days later. I did nothing with the terrain it self, or any assets being used on any terrains even. So i figure it has to be a temp file or something somewhere that is causing this? If anyone can offer me a solution to this problem i would be grateful Thanks in advance, Frans.
