Just extend your borders. You can do this in the Texture Groups window.Just a heads up I've tried repeating a texture from an atlas for batching reasons, it's all fun and games until you try to get mipmapping to work with it. It'll create seams at the borders of each repeat, and GM seems to be missing certain GLSL shader functions that would solve this like the textureGrad function. Not sure why that is.
