INJection Magic allows you to make INJ/REM poses for custom characters, which is a legal way of distributing just the morphs. The person would have to own V3/M3/SP3 in order to use the morph. As far as I know, DAZ's models (both cr2 and obj files) are NOT redistributable in any form, no matter how much you change them. People who make morphs and such for them aren't necessarily changing the model a lot, they're just selling morphs as INJ/REM files which are approved by DAZ. If you're just making morphs using DAZ's morph packs, you can use INJ Pose Builder to create INJ/REM files, which will require the user to have both the model and the morph packs that were used. Hope that helps! - Molly
