Is there a program that can render a minecraft map (overworld and nether) from its seed? I tried Chunky but all I get is a black screen. Mineways only give me a limited area but I want a more larger area. I just want a top view.
I think a combination of JourneyMap and a chunk pre-generator mod would do what you want, at least for the overworld - once you've generated the chunks, you can tell JourneyMap to auto-map them, and then export to an image file. However, a "top view" of the Nether doesn't make much sense, considering it's a cave world with a bedrock ceiling at y=128 or so (unless you're using a mod that changes that - I'm not specifically aware of any such mods, but there could be one)
