I'm using some grey scale images as height maps but the have a "stepping" quality to them. After all there are only 256 levels of grey scale colour so some "stepping" is to be expected.
Is the a "function" way to "smooth" these steps off?
Cheers

ps As far as I can tell Terragen will only accept .bmp, .tif, and .jpg images, have I missed out another format that would be better?
I've only found heightfield smooth works. You do have to soften quite a bit to get the pixelation out, which does destroy details, but you could export out a .ter and add erosion in another app, and then bring that back in.
Sometimes you get better results with an image map displacement though.
Did anyone tried it with HDR images ?

16-bit greyscale EXR, 16-bit greyscale TIFF and 16-bit greyscale SGI images should work. They can be read into the Image Map Shader or the Heightfield Load node.

Thanks , Matt .

Excellent :)

Hmm, cant seem to save 16bit, .exr's and the 16bit tiffs I'm loading are not working either.
Back to the drawing board :)
Richard
How are you saving the 16 bit TIFFs? 1 channel? 2? With or without compression? What byte order?
