Paint tool paints models inside-out?

I have a strange thing happening with detail mesh terrain painting. I am using ojne rock and many are fine looking, but I also have some that seem inside-out. I can look into them and the inside faces of the model show the texture rather than the outside like it should be. Here is a screenshot.


The normals on the models are backward. Go into your model editing software and flip the normals. You might also want to set the import settings for the mesh’s normals to “calculate.”
