So, I recently upgraded to 5.0.1f1 from 5.0.0f4 and noticed that my terrain has a shiny layer has been added. All of the terrain tiles we use are generated via script and are using the "Built In Standard" for the Base Terrain material. Running from the editor, I tried changing the material and noticed that the "Built In Legacy Diffuse" is the Material that removes the odd shiny effect. In the picture below, you can see where the Legacy looks correct and the adjacent terrain tiles have the shiny effect. As a current workaround, I have a small, hidden terrain object in the scene with the correct material that I want to use. Then for all generated terrain tiles, I set the material type to the one from the corrected terrain game object's material type. Really not optimal... is there another way to programmatically reference the built-in materials? Manipulating the direction of the global lighting does not change the effect, neither does disabling lighting from Scene view. Another developer here has not upgraded yet (from 5.0.0f4) and does not encounter this rendering issue, so I can assume that it's something to do with the changes in the version that I am using. Is there a way for me to manipulate the Built In Standard material to not cause this shiny effect? Is this a known issue from the changes in 5.0.1? Or am I just stuck with using the Legacy Diffuse material for my terrain? Update: Also tested with 5.0.1p2 and the effect is still there.
