Can I import models made with Bryce into the TGE?

#1 There is currently no importer for Bryce. You could write one. Bryce doesn't support most of the functionality that Torque uses, and it isn't a very good low-poly modeller, so I don't imagine there would be a lot of demand for it - that's why we don't have an exporter yet.

#2 Also, Bryce for the most part uses procedural fractal based textures, which are really cool, but would be impossible to run in real-time even on the most power of computers.

You could probably bring in the height-maps that Bryce uses for its terrain without too much hassle, though. That would just get you the shape of the terrain, not texture data, etc.

#3 Your best bet is what Alex describes, Bryce is most usfull for it's terrain and sky editors. The terrain grey scale needs to be saved as a 256 png into the editor/common/heightscript folder. then it can be used for terrian generation. The Sky can be saved and used as a skybox.

#4 Ah yes, I had forgotten about the cool sky rendering. Good call Anthony.
