Create a copy of the original .cr2 file.

Open the copy .cr2 in a text editor, I use Notepad ++,  change  forceLimits 0 to forceLimits 1 and save the file.

Test this revised .cr2 in Poser, the limits applied to the parameter dials should now be recognized.

If everything works properly replace the original .cr2 file with the revised edition. I keep the original in an archive just to be on the safe side.

There is some discussion on the non-zero value  to use (1-4) but I haven't noticed it making a difference so I just change it to 1, nothing has exploded......yet.
