I probably shouldn't complain about freebie but what is going on with torso and arms textures intersection? TwiztedMetal isn't known to be complacent but still.

Any suggestions to fix the "arm" textures would be appreaciated. I don't have photshop. I only use GIMP

Moved to Technical Help as it is not a Daz Studio application topic.

I am not seeing this with the character preset or the skin materials presest - are you using any other options that adjust the skin materials? Usually this kind of mis match is down to one of the maps on the arm using a different gamma value from the equivalents on the rest of the figure - to see those you have to select the Arms and Torso surfaces ion alternation, then in the  Editor tab of the Surfacs pane for each map click the nano-thumbnail next to the colour or strength proerpty and select Image Editor from the menu (not Layered Image Editor).

I found the solution. The issue is with the out-of-box Iray skin preset but specifically with Translucency textures of torso and arm. You have to apply 3Delight skin texture preset and then apply Iray uber base. Followed by manually adjusting the colors under surfaces tab. It is a cheat fix for now

Strange, the translucency Strength maps seem to match settings OK for me. I assume this is a fresh download as it is one of the bi-weekly freebies.

I loaded the Absinthe figure and rendered her with the default Daz Studio HDRI lighting. I can see the texture issue reported by @Xeni88. You've said in the past that your color vision is not good. Perhaps you didn't see the subtle color difference between the Torso and Arms. I think the problem is in the Translucency images, not the setings values.

Applying the 3Delight shader preset and then applying Iray Uber shader preset results in the Base Color images being used in the Translucency channel, instead of the translucency images. That is why you perceive this as a fix. The process has removed the "bad" translucency images. But it also lost some of the other Iray settings.
I suggest instead that you just use the Iray preset and adjust the color swatch in the Translucency channel of the Arms surface to get it to look closer to the Torso color in the lighting you are using. It probably won't be perfect. I tried 0.78, 0.57, 0.55 (R 228, G 198, B 194).
Alternatively, just manually replace the Translucency image on each skin surface with the corresponding Base Color image. That will retain more of the original Iray settings than applying 3Delight and then the Iray Uber shader. 
Of course the best fix would be to get the PA to fix the supplied Translucency image. (Note there is also a small visible mismatch between Torso and Legs,) You can submit a help request to report the problem, if you want to. I'll probably just uninstall the product.

I do have to peer really closely to see the line in your image (though so did someone else with non-wonky colour vision).

Great idea. I submitted the ticket. Hopefulelly PA has better trans maps

Lighting makes a difference. It is more obvious in the original post in this thread. It is also more obvious in my viewport than the forum attachment. The torso looks more gray than the arms to me. Although you didn't see it, I wanted to confirm that there was a texture mismatch there.

How about now, minor postwork

The difference between torso and arms is still very distinct there.

One can see the arm-torso mismatch in some of the promo pix
