I was searching the forum for better terrain modeling techniques in Bryce. I came across the following quote from AS in one of the threads.
"How I myself get around this; I use Photoshop to create a 16-bit greyscale image, that is saved as a .tif, and I use a utility made by bikermouse to convert it to a .pgm, which Bryce WILL import that as a 16-bit Terrain."
My question is, are there other freeware, shareware programs out there that can do this( export 16 bit greyscales to .pgm that is) or is this little utility fm Bikermouse available anywhere.
