Same thing with the DAZ Studio stuff.  A lot of it gets installed into the content directory of that program.

What I do, is in my My Documents directory, I have a Bryce folder.  Under my Bryce folder I have "Bryce Projects" and "Models".  Whenever I pose something or set up a DAZ model, I export it into the Bryce Models folder.  

I also have a separate "Textures" folder in there.  I made copies of all of the textures in my D|S content directory and set them up as PSP images (with layers).  That way, every DAZ parametric texture I have, I can instantly change (color, bump ... whatever) by using my PSP image and saving it as a new jpg.

It is also easier for me to find the textures I want when it comes time for me to apply them to the DAZ models in Bryce.  I know that everything is in my Textures folder or one of it's subfolders (like, for example, I have a subfolder for my House Mouse skins and clothing.

Meanwhile, back at the farm, my original textures are safe and sound in the Bryce and/or DAZ content directories.

I have found that most or all of the textures that come over with the models are way too specular and don't have enough bump.  They come out looking like plastic.  So, I much prefer doing my texturing in Bryce.

Could be worse, could be raining.
