worldmachine 2 terrain import problem

Unity Engine
1

OK so i’ve made my terrain in world machine 2-I export the heightmap as a 16bit tiff, i the rezize it in ohitishop from 513X513 to 2049X2049 because i want a more detailed hightmap… now this is what happens

any ideas on how to sort this???

thanks in advance (hopefully i havnt posted this in the wrong section)
EDIT: this happens even if i import the tiff unedited/resized as a 513heightmap

I always export it as a 16bit RAW.

that works thanks but i cant get a 4096 res heightmap if i do that-it says index out of range

any one know whats wrong???

I’ve never imported one that big, likely you’re running into some max limit. Plus, that will generate a huge draw-call eating map. Recommend using smaller sections, and tilling them together. Worldmachine can output maps as multiple tiles.

i still want the awnswer to the origeonal question-i have seen a post with a picture like mine but it was months ago and now i cant find it ):

I need a 4096 heightmap for the type of game ime making-(kinda graphic based as i am now more experienced with unity)

What I was saying was you could create 4 2048x2048 terrains and stitch them together with something like StitchScape. WorldMachine will let you export 4 (or 8 or 16) tiles. This would give you the same resolution. Did you create your height map with one extra pixel around the edges? (ie, 513x513 instead of 512x512)? There is an option to do this in Worldmachine also.

even if i leave the .tiff heighmap and dont edit it whatsoever it still leaves those nasty spikes
EDIT: but that sounds like an interesting idea… so tell me; how do split my worldmachine terrain up into 4 tiles?

and yes the default size it exports the tiff at is 513x513

Stop bumping yourself so much.

Did you use a erosion device in world machine? If so this is why there are nasty noise around the edges. This is because there are no good ways to handle the boundary conditions in certain erosion algorithms. You will always get a 1 pixel area around two of the sides that contains some artifacts. As you have resized the image in photoshop this area is now much larger. You need to trim of the problem areas in photoshop first before resizing

OK thanks

No prob. On second thought not to sure were the noise is coming from but your resizing the height map still would have amplified it and it would still need to be trimmed off.

k i found worldmachine pro 2.2 for free so i can now export it as a raw as a 2049 heightmap (its fine if i export as raw or raw16)
but thanks for the knowhow anyway
