If you click OK it should open a file menu to let you click through to your poser texture directory where the texture is located. If for some reason you have a bug, there's a workaround... Go back to Poser, go to Render pull down menu and select Materials. Look at the names of the textures that you will need in the pull down boxes, etc (I assume you are familiar with how to identify or change poser textures). Make a note of all the textures that you need and then using a file manager like Explorer on win, or whatever fileman you have, and COPY the textures to the same directory where your exported .obj lives. Bryce looks only in the directory for the obj for the texture on import and if it doesn't see it there, it gives the message. Another thing to try, and it helps, but doesn't completely fix the problem, is to run your .obj through a freeware called Grouper before importing. You can find Grouper in the freestuff section here. Likely you will still have to find some textures using the methods above.
