I agree! Bryce and Carrara work as a great team. I love 'em both. I still prefer the terrain/lattice editor in Bryce though the terrain editor in Carrara has its own strengths. I've been experimenting with exporting some of my displacement modeled rock outcrops from Carrara as an .obj file with the corresponding texture file. They import almost instantly into Bryce, and can be used on their own, or used to make an altitude mask to be used as a heightmap, for terrains or lattices in Bryce. I can make terrains that would be hard to achieve any other way in Bryce. I can use the same heightmap and texture files back in Carrara as well, so they can be doubly useful. In case you haven't already tried this, I've posted here a heightmap and mapping texture,  Cheers, Dan
