I'm using a Mac, BTW.
I want to export a terrain from Unity, perform some manipulations in GIMP (want to raise the terrain uniformly so I can carve deep valleys), and then reimport back into Unity. I'm having a hard time with the import to GIMP, as everything is grayscale but GIMP only seems to understand RGB RAWs.
Anyone seen, hopefully conquered this issue?
If GIMP simply can't handle grayscale RAW images, is there any other (cheap or free) Mac-friendly image editing software (or dedicated heightmap editing) software that folks can recommend?

How are you doing the export? DEM's (if that's what you're doing) are generally 16-bit grayscale. If GIMP can handle them, then it should be ok, my version (2) does not seem to have that.
I'm exporting the heightmap by choosing Terrain->Export Heightmap. Is there another way? The only options I see when I export the terrain are Depth and ByteOrder. I'm choosing 16-Bit and Mac, respectively. It then makes a 16-bit grayscale RAW image.
Thanks for your help!
Looks like you'll need Gimp 2.8 http://www.gimpusers.com/tutorials/gimp-2-8-new-features
Yeah, it looks like that's exactly what I need!
