Plastic material for Terrain

As a Roblox developer, it is currently too hard to make low poly looking terrain with current terrain materials.
If we had clean material like plastic without reflection it will be a huge improvement for low poly games that actually use terrain.
Every time I want to create no material terrain I must make it in other software (Blender etc.) and then export it and after if I want to edit it it is really painful.
That one brush preset will help us, developers, achieve what we want with the terrain.
