Efficiency.

LF2toV4 I only have to do once.

(So far I invested about three hours, but I have done something like this probably a dozend times.)

After that, gazillions of V4 clothing items are just one mouseclick away.

How long does using the cloth room take to just convert one piece of clothing?

(Don't laugh, but I actually never used it, because I developed my own pipeline of fitting cloths long before the fitting room)

But, anyway, this was basically just a test if it could be done while preserving the original facechip rigging.

(It still confirmed my original opinion, though, that the more "primitive" a figure is rigged, the easier it is to modify it to suit your needs)

V2 came with a V2Posette companion figure. V3 with a V3toV2 figure. (Which could even use V2 textures).

V4 had a V4toV3 companion.

DAZ did this, so that the new generation always could at least use the clothing of the previous generation, unless it could gain enough traction on its own.

People want clothing. And a fresh face.

They don't care about elaborate "clever" rigging. (Not to mention that even "primitively" rigged figures can bend very, very well, which I've proven several times in the past)

V4's wardrobe is a huge, huge mountain now.

Unless you can pay hundreds of top tier PAs to match that enormous mountain of cloths right from the start, or come up with a true "one click", ultra fast and super-accurate cloth converter, I see this as the only way to make a new figure truly competitive.

In this case, you literally CAN have your cake and eat it, too.

BTW, I truly despise V4's default shape with her weird triangular thighs and her non-existing knees. (She was designed that way, so she could share a cr2 with Aiko 4, given Poser's original scaling limitations)

But it's very easy to modify LF2toV4's shape into something more realistic looking, and then one-click transfer that new realistic shape into V4's clothing items.

Which brings me to the next step of this tutorial:

How to transfer V4's bodymorphs over to LF2toV4.
