Well, I thought I'd figured out how to INJect ShaderNodeParms (those parameter dials you get in the Pose room when you animate a value in the Material room). It turned out to be rather simple. In the pose file, I use the "createFullBodyMorph" command and then just identify a ShaderNodeParm with the same name subsequently in the file. The PZ2 does three things: 1) create master dials; 2) create ShaderNodeParms and enslave them to the master dials; 3) apply a set of materials that reference the ShaderNodeParms. It works swimmingly, or at least, it seems to. The problem is that Poser crashes whenever I try to save a scene after having applied the PZ2.

I'm suspicious of the fact that it has something to do with the injected ShaderNodeParms, since INJecting them is very experimental on my part, and I've never had any trouble doing anything else that the PZ2 file does. Anyway, I would greatly appreciate any expert advice here.

Upon further investigation, the problem may lie not in INJecting the ShaderNodeParms but in linking the material values to them. If I apply a version of the pose that doesn't apply the materials automatically but does everything else, then it doesn't crash when I try to save it. But when I then apply the material collection separately, the links between the shader values and the parameter dials aren't there

I suppose I shouldn't be surprised. I've sometimes experienced those links randomly breaking after saving a PZ3 or CR2 anyway, even before I began experimenting with creating those links via INJection pose.
