Hivewire have just released Dawn SR2 as a free update. Downloaded though not tried out yet, but here's a copy/paste of the changes:

** SR2 List of Changes**

• Poser- Added 53 new morphs and 7 controls
• Added 6 JCMs to improve thigh movement
• Fixed drifting points in elbow when morphs are applied
• Fixed Size morphs to get larger when dialed in the positive
• Re-organized dial catagories for ease of use
• Updated Gamma settings to 1, for bump, specularity, and transparency maps
• Added conforming lines of code to clothing resource kit
• Existing Dawn figure will remain so that you can still use her if desired

Cool.  Thanks for the update.

Still no shoulder fixes :o(

**JVRenderer -  Would you post a render/renders of the areas that you think need a fix and post which rotations and their values are producing it?  Right side if you would.

Still no shoulder fixes :o(

Indeed, her shoulders are not as dainty as V4's. She's a strong one, that Dawn, with wide shoulders like a good ole country farm girl that has no trouble carrying a pair of eight gallon milk jugs. Her delts aren't nearly as overdeveloped as V3s, but they are noticeable when her shoulders are down. I'm not certain this is a flaw so much as just a normal human variation. I'm also reminded that many joint problems can be solved in a matter of seconds with a few swipes of the morph brush (smoothing fixes almost anything). I used to find using the morph brush to be very difficult and unintuitive, but after adjusting the parameters to a give a much more subtle effect and practicing with it, I now find it indispensable. You might give it a try. But it does depend on exactly what it is that troubles you.

I've had luck with just scaling the shoulders a bit but there is still something a bit odd going on in the bicep, shoulder, armpit area. I can't see that being fixed in an SR as it would probably mess up the fit for conforming clothes. It is what it is, I still use her on occasion and Dusk doesn't seem to have those issues. He appears quite nice actually. Happy for the free update though.
