I'm experimenting with taking section out of a Terragen scene terrain and importing into Gaea to add morer detail.
I've got a good method of exporting an exr as a heightfield (see:
https://planetside.co.uk/forums/index.php?msg=213591)
But that heightfield has absolute values for the terrain, Gaea seems to like normalised heightmaps when importing as a File.
Is there an app or prog that can normalise heightfield? Or a formula to work it out? At the moment I'm passing the heightfield from TGD through World Machine to normalise it, but getting the right height at the moment is a bit of guesswork.
