Sounds a lot like you have your morph(s) compounding one another in some way. The reason Jaager gives for using Ray Dream Studio for his morph creation is that it's very precise in the way polygons are selected & moved. If you do morph creation within Poser from scratch, using the Grouping Tool, it's easy to get bizarre & unexpected results because if you're not careful, you can accidentally select an unnoticed polygon & group it with the ones you really wanted to select. I don't know if that's the method you used for your morph, but I know it has happened to me in the past & the results were similar to what you describe. Since then, I've acquired RDS & once I master the program, such problems will hopefully be reduced or eliminated.
