There are a few different ways I would go about this, personally. Keep in mind, too, that there is no right and wrong with this: if it works, it's right and that's all that matters. 

Skin Weights: following through with what seems to be your starting point currently, you would need to get very nuanced with your skin weights. One of my personal tricks for working with them, especially on something like this, would be to animate it over about 20-30 frame in it's most extreme poses; in this case, it would be from completely open to completely closed. From there, I would use the left and right arrow keys to walk back and forth, frame by frame, while keeping the skin weight tool open, making small changes as needed. On something mechanical like this, you will probably be able to see the values that work best once one of the ribs is done then mirror the weights to get quite a bit taken care of, then, probably down the center, reproducing what you observed on another to get those brought into line, Be forewarned, though: this can be a tedious process. 

Morph to joint linkage: a simpler, more backward/cross compatible method would be to have the canopy of the umbrella morph between, let's say, closed, open mid and fully open, then put a dial on the handle and set these three morphs to be driven in succession, then link the arms to follow this at each of the keys where a morph is dialed on. The tricky part is that the morphs would need to turn off and on exactly right or you can end up with some strangeness, but that's only if you're doing multiple. If it can be a simple 2 morph solution, then the vertices can move along a relatively straight enough vector that making the bones follow and linking them up to that is not that hard. 

I apologize for not pulling up an example right off and posting any screenshots of what I'm talking about here, and since I'm speaking more conceptually than specifically, if something mentioned deserves an illustration of some kind, just let me know and as soon as I have a moment, I'll be sure to pop something in here. -Les

Thanks!

Hello, Rebekah of Sixus1 here.  Stopping in to give an update.  A service release for Scarlet is pending approval and will be available very soon.

Addressing concerns voiced by our customers we have made a few additions and a couple of changes to Scarlet. They are as follows:
1.) Joint Parameter / Skin Weights adjustments on the Hip/Thigh area

2.) Eyelashes - 2 morphs have been added for the top and bottom lashes for user preference adjustments on placement of the lashes & the Lengthen morph has been changed

3.) Scarlet's material settings have been changed to work better with the default Poser render settings regarding gamma correction

 
If you have ANY questions, concerns or comments, please don't hesitate to contact me.  Thank you for your support!  We have much more Scarlet products, packages, morphs, poses, kits, tutorials and resources coming...and if you have any requests please send them our way so that we know exactly what our users are looking for.

Over the last few years, our studio has turned out around 60 or 70 animated character pieces for the augmented reality apps attached to books from Brian Haberlin's Anomaly productions. Most of that started with assets he had put together and customized inside Poser in some way. Since a lot of that came from our catalog of monsters and aliens to begin with, it was a good fit for us to come on board and help finish out those productions, but Poser was definitely the starting point. In the past, as well, we've actually used Poser as a low cost animation tool where we would build custom game res figures, rig them for Poser while making sure to have certain compatibilities across the characters that would then allow us to use Poser's pose/animation capabilities to repurpose a lot of animation data across as many as a couple hundred characters in the course of one particularly large production. 

Currently, we're making extensive use of the new Game Dev version of Poser (albeit in conjunction with a lot of in house tools built up through the years) to produce a 1v1 fighting game for Skystorm Studios/Afterburn publishing. Again, most of what we're doing is custom built pieces, but there are some very unique aspects of Poser which, combined with our experience and in-house tools for content production make it an obvious part of our pipeline. -Les

Nevermind....

 Seems to be working for me now in IE.

I am having the same problem.  Front page loaded for a split second and then just went blank.

Works fine in Chrome.

I agree.

I don't know how you are making your INJ morphs, I always do mine by hand.  Underneath the name of the morph there is a line that needs to be set to '1'

valueParm PBMCC_01    
{    
name Fireball    
initValue 1    
hidden 0

If it is a linked up Full Body Morph, then set it on there only. If it isn't linked up to a dial on the Body, then do it for whatever body parts you want it applied to.
