I experienced weird skyboxes to appear when applied conversion from Unity 4 to 5 in my asset. Weird thing is happening with clouds, where brightest areas are becoming black. Here is the result with Sunny1 Skybox: I also can't disable-enable skyboxes, as doing so does not change visible skybox. Skybox also remains if I remove "Skybox" component from MainCamera. Does anyone have idea how to fix this?
