I was wondering if any of you have any ideas that might help me out here? Basically, my game uses isometric ground tiles and we want to find a way to produce a lot of them at once. Ideally I'd like to be able to do a large grid of tiles, perhaps 10x10, all at once - the painter would paint say an entire field, and then we'd automatically slice it into individual tiles. If this was not an isometric grid, this would be really easy - Photoshop can Slice by Guides. Unfortunately, it can't support diagonal slices as it doesn't allow diagonal guides. As isometric tiles are essentially diamonds, this is a bit of pain. Does anyone know any program that is able to do this?
