Why would it be that when I paint my on my LIDAR surface it doesn't save the painting I did. Example: if I try to blend the simi-rough areas of the course by painting in a texture at the edge of the spline, Unity doesn't save the painted texture. The next time I open the file, the painted areas are back to the original lidar.jpg.
It makes sense to me that you need to be careful here because if you paint over something you need to see, you wont be able to see it. That said, it seems like you should be able to do this? What am I missing?
EDIT: its not just painting its also changes to terrain.
