Yeah man! you are right! It's the wacom service that is causing the error! I had the wacom service running. and speedtree wasnt working. I stoped the service and it started working. Crazy
@frostymoose: You might want to give Ariel Chai's pipelineIO script a try. The new service pack 5-2 for Modo might also help with exporting proper vertex normals to xNormal, though you might have to use FBX or Collada. Also check out the Normal Maps: Can Somone Explain This "Black Edge" issue thread especially EarthQuake's…
