--- Quote from: monks on January 21, 2014, 10:11:43 am ---I'm in the middle of a game project for a studio and all of my me-dem projects are on a backup hd because I ran out of space on my computer. So I can't render anything out. The old renders are nowhere near the finished state of the latest terrain, it's not worth using to be honest. I can have a look to see if I still have the original output files from the last render before it got converted to the Outerra native format. Other than that, folks will have to wait a couple of months- could be a little as a few weeks- before I can go again.
 Our "policy" for want of a better word, is to not give out the terrain at full res. We could give you a 10K terrain and you could always upsample it.

I'm gonna' respond here since I don't want to off-topic the intro thread.

Since Minecraft has a height limit of 256, an 8 bit heightmap would be sufficient for my needs. I have no idea how getting an 8 bit heightmap from the elevation data would work, but if I have to wait...I'll wait.

When you say '10K terrain' what exactly do you mean? What's the dimensions? As a reminder I'm shooting for at least 24000x24000. 48000x48000 would be better!

So...no 8 bit greyscale heightmaps lying around? Doesn't have to be latest version or anything.

Take care.

I thought middle earth was done in mine craft. I saw the Hobbiton and Bree on some forum somewhere. You can check out the galleries I am not sure we have an 8 bit version anywhere. All of the stuff we use is float based height. I am not sure that 256 levels would adequately encode a terrain height. If you had a mountain 25600 ft tall then your res would be 100ft per value.

monks:
We've got a 40K map in 64 tiles I think. I can't guarantee that it's the latest terrain. The folder says "previous terrain" so I think it's the previous terrain we ran- but again I can't guarantee that.  It's generally too high to be realistic, but it is nice visually. You can have those but you'll have to reformat and resize them yourself.
 I might even have the latest one. What's the name of the folder in the Mainmap directory where tiles are output Robes?

I dont think we have a greyscale bitmap of the heights only. I think we would need to write a script to generate them if we needed it. We have only got HF2 type. We have a black and white only mask of the land sea at 10K res which is a good start. And we have a black and white mask of the hilly ground at same res and we have a mountain mask as well so we have a two bit solution... Those are in the preprocess 10240 section of the main map files and the Tiles Level_0_10240 section. Not bad for Minecraft tho -maybe ???

monks:
Looking at the scripts, the tiles are output in C:\MEDEM\Mainmap\CalcTiles\Level_0_5000

I've got the latest run in there in the OuteraHeight. dir Yep 64 5K hfz. If you want to knock up a script Robes, convert them to 8 bit or whatever he wants them in...or if you're really busy I could just open them in WM and spit them out. That's if my computer has the hd space for the processing. I'm down to my last 150 GB. Prob easier with WM...I'll try it.
What format Morcrist? World Machine has TGA, RAW, BMP....
