Before and After skin texturing

I recently upgraded my computer to pretty much state of the art in all areas. I do only Iray renders. What I find curious is that when I load many of the G2F and G3F figures, their skin textures look a great deal different then how they look when rendered. My question is this... How do the people who create these skin textures know what the finished rendered image is going to look like? Surely they don't make a change, view a render, make a change, etc., etc.... Thanks.

    It's mostly due to experience. Like you, I only like look the unrendered scene better than the rendered scene, at least as far as the way the highlights on the skin and skin tne look.

    I asked and was told their are two things that most of the artists that have products in the store do to create the pictures for their products in the DAZ Store:

    1) Set the translucency weight to be a smaller number. 0 = no translucency only diffuse texture and 1 = 100% transluncency and no diffuse texture - well no quite but generally low transluncency equals lighter skin tone and high transluncency equals darker skin tone, mostly because more of the deep reddish brown transluncency color shows through at higher transluncency weights. You can change the translencency color to a lighter peach pink, white, or shades of brown for darker or lighter skin tones if you like.

    2) They use Portrait Lighting - and that creates the sort of contrast and highlights similat to how the openGL preview panel shows if you are careful position the studio lighting to create similar lighting to the preview panel.

    Hopefully an expert comes along to offer you even more effective tips.

    Thank you for that help, however, what puzzles me is if you have to render a figure to see it's final look... which can take several minutes, it doesn't seem efficient to make a change that will effect the figures skin tone, then stop and render the figure to see if it looks as desired... and then make yet more changes, each time having to waste a lot of time finding out what the rendered look will be. Hope that helps to clear up what my question is. Thanks.

    It doesn't take minutes. Just pick NVIDIA Iray as your viewport (see attached).

    I always do this when altering skins or applying shaders. The results can be seen in seconds since the entire scene is already loaded into VRAM (it's not a complete render, but it gives you a very good idea of the final result).

    This is assuming you have a GPU which is capable of fitting your scene.

    I go back to Texture Shaded when I'm done playing with shaders or skin tone so that navigation is fast.

    There is a tiny aux viewport you can turn on NVIDIA Iray to see what you final image will look like. You need a good nvidia card to use it though.

    Thank you for the great help. This will definately make things easier. When I started with Poser and then went to DAZ, I never realized that it would almost take a college degree in 3D graphics to have fun with this stuff. BTW... my current system uses an Intel I7 6700k 4GHz processor, Zotac GE Force GTX 1080 8GB video card, 1 TB SSD, 2 – 3 TB drives, 1 5TB drive, 3 Asus 24" monitors, and 64 gigs of RAM... and I still get impatient doing Iray renders... LOL
