So I have bought/created enough Gen 4 material now that I load up a base figure with all the morph injections.  The Daz stuff works pretty well, but third-party injections like to overwrite the Daz channels in the figure.  I thought it had been discussed a LONG time ago, but I can't find anything.  Other than hand-editing all the injection pz2s to sort out who gets to use what channel, is there a better way to deconflict the morphs?

This should not happen as there are 2 types of channels: DC and CC.

The Daz-Channels should be for DAZ-Injections and the Community Channels (CC) for the rest of the world.

Are you sure you are using the V4.2 cr2 and not an earlier one?

Nope. The only way to really avoid channel conflicts is to turn the morph set into EXP files (like the major morph packs from DAZ and a few vendors).
This is more work than reassigning morphs to different DC or CC channels.

Maybe a silly question, but do you know how to do that?  I did some research b/c f your post and was led to the EXP Exporter tool in Daz Studio.  Got it to work, but it only created inject/remove files, which I could have done on my own.  So I edited the inj/rem pose and geometry pz2s manually with the Daz ones (morphs++, etc) as a template, and it worked to bring the morphs into their own channel, except that they overwrote the "strength" dial under the Deformers tab.  It happened as Poser went down the list of readscript calls in the injet pz2, so the last morph in the pz2 was the only one injected by the time it finished loading.
