I've been following this thread with great interest since I'd love to use most of my outfits on V4.  I have WW and like it, but there are some things that I just couldn't get a decent result on (maybe user error! lol).  Things that were mentioned earlier in this thread - straps, buckles, surface details didn't come through the WW very well, based on my brief attempts.   Someone with more experience would get better results, I'm sure.

This CrossDresser has done some great conversions for me - and I've only had it for less than a day.  Here's an outfit I had problems with in WW - Eclipse by AS - took less than an hour to convert all the pieces.  V4 looks pretty happy about her new outfit!

I did what was suggested earlier in the thread - unchecked the option to have XD regroup the item so that I could use MorphManager to add back AS's excellent movement morphs.  Worked like a charm!    Next outfit I'll try converting is RDNA's Oktapussi from A3 to V4 (lots of strappy things on that outfit too).

I think I'll end up using both programs as they serve their own purpose.   I was most impressed at PhilC's attitude about the new program - that competition raises the bar & he even wished them much success.   Kudos to him & to EvilInnocence for bringing us a fun new tool!
