I've upgraded my map materials, and are using the JRI terrain textures, but my map is showing up black. I have tried to make my own grass texture and set the JRI textures to it, but it still shows up black. Changing back to 1.0 seems to work with displaying texture, but doesn't work with the new textures I have. (the grass ground detail shows that grass has been painted down) I was hoping i could copy over the JRI main.materials.json, but nothing changes in the map. Help would be appreciated
