I should've guessed people would want to get a spreadsheet of all materials. I had a half-broken internal dev tool that printed out all material properties (and costs) to a csv. Figured it'd make your lives easier if I just fix it up and expose it to users. It'll be in the next update.
This can be accessed as of 1.0.7 now, via "PrintMaterials" added as a command line arg. It dumps out a csv to the save file location.
