Painting 2 different textures on the same landscape chunk causes the whole thing to revert to default texture

I have a landscape which I am painting, and it’s working fine except for when I have 2 different textures on the same landscape chunk (IDK what the squares that make up the whole thing are called), then the whole chunk turns into the default texture until I clear the textures from the map. The textures aren’t on top of each other, just in the same square. They work perfectly fine otherwise though, any idea what’s going on?

You’ve run out of texture space. Go into the material, click on each texture, and change sampler source to ‘shared: wrap’ :slight_smile:
