10k x 10k Minecraft Map - Best Way To Export?

Hello World-Machine Forum,

I'm currently in the process of building a rather large 10k x 10k map for a Minecraft server.  After generating the terrain in Worldmachine, I aim to composite the heightmap .png files in Photoshop, then import the final terrifyingly-large heightmap into Worldpainter, where I'll use the exported flowmaps and depositionmaps as custom brushes, before exporting the final product to Minecraft.  The issue I face is the sheer scope of exporting, while also saving the flowmaps and depositionmaps at the proper resolution - Worldpainter's maximum brush size is 600x600.

Is there a process by which I can export a series of 512x512 tiles, for heightmaps, flowmaps, and depositionmaps?  I've read about tiling exports - would that be suitable in this case?

Thanks for your help - If this works out, I'll post some pictures of the exported landscape.

EDIT: While using Nikita's Dunefield macro, I found a trick to make it tile infinitely - I was having issues after I'd expanded the extents.  To make the Dunefield tile infinitely, enter the macro and change the tiling of the first two gradients to "Linear"

I'm not familiar with Minecraft or World Painter, but the tiled export does exactly what it sounds like you want (not sure if that's actually what you need). Basically you specify how many tiles to subdivide your current extents into to, set the resolution for each tile, and every output device will export however many tiles you specified.

You said that you're going to combine all of the tiles in photoshop, but I don't understand why you can't build one heightmap in WM, unless you're hitting RAM constraints for a low pixel:meter ratio, but I thought Minecraft was rather simple in the terrain department.


It's really simple, in the WorldPainter settings you can change your maximum brush size :)

For more questions about Minecraft maps you can ask on the WorldPainter subreddit http://www.reddit.com/r/Worldpainter/ so we can avoid spamming this forum with non relevant content


Thank you Peregrinus and JakBB. Those are the best answers I could have hoped for - one explaining exactly what I needed to do, and another explaining that I don't necessarily need to do it.

As to why I wanted to use a tiled export - I was under the impression Worldpainter only supported brushed up to a certain resolution, limiting the resolution of each exported tile.  I'm very glad to know this is not the case.  I'll definitely head on over to that Subreddit, and post updates on how the landscape is going.

Thanks once again.
