@Penadraia: First the bad news: Netherworks has apparently gone refugee since the DAZ Anschluss of RDNA, and I can't find his utilities for sale anywhere. Hopefully he will resurface. But if you have it already, the user's guide explains it all. The instructions are geared to transforming Genesis 2 figures and content, but they work fine on anything. In DS, load the figure/item, select it, and select file>export. Pick a destination folder; the file type should be preselected as cr2. Make sure Save Binary Morph File (PMD) is checked and click accept. I always put it in a folder for exported DS items in the Character Library. Go to Poser and load the cr2 (see below). If the product has a PoserCF for DSON, just load it.
The G2 process has a step where you first conform your DSON or imported cr2 (for products released without DSON CFs) to a DSON G2 figure so the clothing will adopt all the morphs. Then you save it to your Poser Character library. For a Dawn product, after loading it, save it to the Character library. This copy is the one you will convert.
Fire up Creators Toybox File Optimizer. There is a button in the lower right for Presets>Core Presets>Convert Saved DSON Accessories or Convert Saved DSON Figures. Use the first for clothing shoes, props, etc. Use the second for figures (e.g. Monique 6). For a Dawn item, you would choose accessories, unless you are converting Dawn herself (I converted Dusk Nataani that way).
The buttons on the right side let you convert all sorts of things. For clothing, shoes, figures, etc, pick Figures. Click the box and select the converted item from the Character Library and say yes, you want to proceed. Click copy. This will solidify the (I assume temporary) DS obj file. I created a folder in my Runtime geometries folder where I store all conversions. I learned you want a new subfolder folder for every item or your list gets way too long. Save your item. Toybox will churn for a few seconds and then tell you optimization is complete. You can now load the cr2 as fully native Poser. It will conform properly, but you may need to import morphs from (in Poser Pro) or use the fitting room to match a morphed figure. I imported morphs from Jenny in the above image.
There may be some alternative script to Toybox, but I have never investigated that because Toybox is easy and seamless. I hope this helps. Cheers!
