You should get an error message in Bryce after trying to import the Poser object (.obj), asking for a .tiff file,Then Bryce might even crash! if so, just make a text file with the object.tiff in the same location/directory as your poser .obj file, then it should fire right up. The txt file can be trashed later.

Do atleast one thing a day that scares the hell outta ya!!
