I went to redownload Matmatic from bagginsbill's site only to find the site has gone - no big problem as I found primorge's thread about that and found it on the Wayback Machine (8 captures 4 Feb 2009 - 20 Oct 2020). Downloaded all versions (each download sent me to an archive.org page that said it was redirecting, and after a short while during which it appeared that nothing was happening the download started. So it would appear that patience is required)

I recently had to reinstall everything from backups and I initially got that "No module named matmatic.compiler" error - obviously the backup I used had the Poser 5,6,7 beta version.

So I deleted that and installed the latest 1.6.0, along with the documentation (separate download) and the Matmatic demo (just the .mm1.txt file)

Matmatic runs okay (compile.py), although it tells me in the debug Window that it's 1.3.0, but it doesn't appear to actually compile the .mm1.txt

My Poser 11 is installed in the usual place C:\Program Files\Poser Software\Poser11\

My default Poser runtime is separate from that, in C:\Users\<me>\Documents\Poser 11 Content\

I've put Matmatic in C:\Program Files\Poser Software\Poser 11\Runtime\Python\poserScripts\matmatic\

I have one MM1 file to test things C:\Program Files\Poser Software\Poser 11\Runtime\Libraries\Materials\MatmaticDemos\PP2012\PP2012.mm1.txt (as I said before, JUST the MM1 file - no timestamp file, no MT5s/MC6s)

When I run compile.py from the Poser menu File > Run Python Script (verbose set to 2 in config.txt) I get this, which proves that it's working

There's no indication that it's found the MM1 file , and when I look in the MatmaticDemos folder nothings changed.

I'm almost certainly missing something obvious. Can anybody help ?
