8kx8x Environments. Unity Terrain Or ?

I am looking for giant terrains, and I notice you could set the unity terrain to whatever you want, so I set it to 8kx8k to see as far as the eye could see. But what I want to know, is for big worlds like this, would there be a better system to use for a large terrain like this? or bigger?

Also a good tool to make generate a random heightmap to make big continental type islands, for a good healthy random environment surrounded by ocean. The borders of the playable area would be quite a distance out in the water.

Anything you guys think would be best for this? I was looking at Proworld on the asset store, but wouldnt heightmap resolution need to be 8kx8k too? The biggest heightmaps i seem to find are 4x4.

I guess a better question would be what is the biggest First Person environment anybody has ever made with unity getting good FPS. I need a huge world. Ridiculously huge. Complete with Foliage.

The default terrain should work fine, although try to have quite a few hills and valleys, then bake a high res occlusion culling on it. Something that large wont run on a netbook, but for most pcs it should be fine

Yeah. Targetting higher end PC’s anyway. But what could I use to make a heightmap so large to get an auto generation for the land features?

World machine, but you’ll need a decent PC if you don’t want to use tiled rendering to generate the maps (tiled rendering can create artefacts).
I can personally confirm world machine works just fine for 128 000 X 128 000 maps (heightmaps, colormaps normal maps generation)

holy god 128k by 128k?? I have a decent pc :wink:

The issue you’ll run into is ram for very large resolution. 64gb was only enough for trivial graphs at 128k. But at 8k you shouldn’t have any issues

Yeah I couldn’t imagine something as big as 128k. But in the range from 8-16k I could see some good stuff happening. $90 though dayam. I would have to be able to somehow see some good auto generated environments from this thing on that scale working in unity before I paid for it. You say you have it?

Yea i own it it rocks, really user friendly. Just download the free version (resolution limited) so you can see how it works

513x513 though. I would want to test with something bigger… Can I PM you?

Sure, but really test wise 512 should help you see how it works, after that just need to buy a regenerate high resolution.

After making an 8k texture, I dont even want to pretend to imagine how intense an 128kx128k map would be…
