You can use a text editor to create both kinds of poses, I wouldn't want to do it that way though, but if you can find a CR2 editor that works on a Mac it isn't very hard. I create my MATs by taking the saved CR2 and editing out everything but the version number, figure line and the materials themselves. You can use a existing MAT as a pattern. INJ/REM area little harder, they normally run in two sections, a PZ2 file that calls anothr file that does the actual work, plugging the information (deltas) into the CR2. I patterned mine on the DAZ ones, except I don't run my REMovers as two files, as all they do is turn some information off. The idea on the two files was to keep the filesize down in the actual pose library, I gather.
