Thank you for your help You're very thorough. I updated from 2.6 to 2.8 and changed Max Texture count to 8 and 16 and tried full (and everything on). Those didn't work so I recreated part of the seven. Could you et me know where to send it? Im using Unity 2019.2.8 In the scene you might have to press play for the textures to generate - sometimes the terrain textures go flat when I press save. You can change the UV Resample size in the MicroSplatTerrain texture to see the effect - the grass changes uv size but not the snow or the rock.
