AFAIK, all of Phil's add on support for WW are for humanoid bidpeds. It is my understanding that Posette is the base or the original figure used in both WW and Puppetmaster. The problem with satyr's are the leg shapes. While the satyr's are biped, the goat legs cause problems. The shapes are just too complicated. Doesn't matter if it's an original figure, the V3 satyr or the V4 creature morphs and legs. It's either take the pants into the modeller and fix it by hand or simply hide the parts that are poking through as much as possible while using the morph brush to fix as much as you can.

Elves depend on the base figure they are morphed from. I have several elves that are heavily morphed P4, D3, SP3 and Gen 4 figures. WW can convert and add morphs. I do have to use the morph brush on occasion to do some final clean up on the conversion but that's minimal.

You might want to look at Marcus Dunn's Clothes Convertor over at DAZ. This is the only conversion app I know of that allows you to make conversions for original figures. This is a windows only app. You also might want to submit a ticket to DAZ CS asking if the app works in Win7 or higher. I haven't used it since vesion 2 and I know that the same vendor's Pegasus modeller had issues with Win 8 at one point. This app like all convertors has it's good points and bad points. The good points for you is that it doesn't require any other add on products and you can do conversions for original figures. It does have a bit of learning curve and conversions vary.

DAZ's PA sale is coming up next month so at some point, you should be able to pick it up for half off.

If you really need the .dat files for WW and are willing to pay for them, site or email him. The last time I discussed it with him the cost was $100 for the .dat files for each figure.
