Question about .raw file format, going between world machine and unity

Alex_J

Hello, 

Unity terrain requires a .raw file format for heightmaps. World Machine can output this, however the file extension becomes either .r16 or .r32. The only type of RAW file I can export is low precision 8 bit, which results in bad banding on the final terrain.

I am playing with magic here because I don't understand exactly what these file formats mean exactly. Obviously bigger numbers = higher resolution. And 8 bit won't do. But can I convert these .r16 and .r32 files so that Unity recognizes them?

Thanks!

Never used World Machine with Unity but I've fiddled with Unity terrain, which expects the height map to be in a 16-bit RAW format. I'd assume that you can just import the .r16 to Unity or just change the extension to .raw in Windows and it'll work just fine.

World Machine has workflows on their website for different applications. https://www.world-machine.com/learn.php?page=workflow&workflow=wfunity

One Warning: Unity interprets raw heightfield origins differently from World Machine; your terrain will appear to be flipped on the Y axis! One way to fix this is to add a Flipper device in World Machine just before your Height Output and turn on the Y-axis flip. This will make the terrain export identically.
