is there a way that i can create a terrain in hex or some other modeling program, import it into Bryce, and have Bryce recognize it as a terrain object??

TIA

    Model it. Render a height map from it in the render software of your choice. Use that height map to create a terrain in Bryce.

    just tried that and does not seem to work.. cannot preserve the contrast range needed to reproduce the original object.... need something a bit more direct.

    thanks!

    Its possible the height map from your other app is not creating a 16 bit image.

    It is possible, but difficult. I have done this with Grome 3. There are heightmap exporters but the trick is setting the range and getting it to output in a format that Bryce Terrain editor will accept. You need, 16 bit precision and I use tiff. The picture radio button in the Terrain editor will let you bring these in. But I warn you now, it is a time consuming and fiddly process, cross calibrating the two applications.

    These scenes (taken from the Bryce Mentoring DVD ) are examples of heightmaps generated using, or filtered using, Grome 3.

    You can also "paint" a height map in a graphics application where white is high and black low. It must be exported as a 16 bit greyscale (not colour!) TIFF. Back in the terrain editor of Bryce, you can use the filter, erosion and what-not tools to adapt the terrain.

    well.. this whole thing started because I had come across a modeling program that has a terrain generator/editor included with it-- VoidWorld.

    Below is a screenie of it.

    And also a terrain in Bryce that was created by the program.

    The problem was that exporting from VoidWorld as an obj, and then importing into Bryce, I could not apply terrain textures or height maps to it... hence my posting.

    However, Horo's comment particularily woke me up. I had not looked at VoidWorld close enough! It will also save the image map as a bmp file, which of course, imports directly into Bryce!

    So here is also a shot of it imported into Bryce and a quick render. I had to lower the altitude a bit when importing, but othere than that, there is no manipulation to the image.

    Thanks all, for waking me up and making me think a bit!
