Moogal,

Have you ever been involved with software development? I have.

There are a series of trade-offs involved. Will the new feature sell enough copies of Poser to justify the cost of developing (AND supporting) the new feature.

People haven't been demanding a better dynamic cloth room - they have been demanding that SM (and e-Frontier, and Curious Labs) fix the d@#$%d UI to where it is comprehensible. It helps that we are finally to the point where the hardware isn't brought to its knees when doing a sim. (That has actually driven my computer purchases over the past decade). People were whining about the render engine. Superfly is easier to use than either Reality or LuxRender. Poser users want a 1-click solution, not a 3 click solution. And they are cheap.

I am sorry you haven't found any use for all of the new features that have been added over the years - myself, I couldn't go back to Poser 2014, much less earlier versions.

bust out the seams of their clothes when I bend an elbow. There are multiple solutions for this. Use dynamic clothing (the easiest); Merge clothing and figure into 1 figure; remember to magnetize clothing; add missing body morph; use the fitting room; use morph brush.

lose their hair when I turn their heads. The fact that you forgot to parent the hair figure to the character isn't a software problem.

Why not a hybrid sim that lets you conform your clothing and then makes it part of the original figure, and maintains relative distances throughout posing. Have you looked at the properties tab on the clothing? Match Endpoints; Follow Origins; Include translations should address those. Or use the Combine Figure command.

I was asking for a way to replace a body part with an arbitrary mesh and have it seamlessly blend in to the figure, irrespective of UVs, materials or grouping. You have Zbrush - sculpt what you want there and import it into Poser as a Morph Target.

I don't think Creature Creator did what you seem to think it did (As an added bonus, you couldn't undo a number of the morphs once they were used). We've been able to adjust scaling (and moving the joint centers) for a few versions now. I'd recommend spending some quality time with the joint editor (accessed from the Windows menu). Not only is it covered in the manual, SM covered how to do it in webinars back in the 2012 era.

Using your t-shirt example, we have that already - it's called dynamic clothing.

I would suggest that you submit to your requests to SM (There is a Submit Your Poser Suggestions to Smith Micro). As a minimum, you might want to spend some quality time over on the SM forums - that is where the action is. C'mon Project E.
