Use

══════════════════

Using the Daz Studio's material selection tool, select the surface you want to match with the photo

for example i select Aiko3's SkinTorso material

This also selected the Aiko figure . Note that the root node and only the root node of the figure needs to be selected.

Move your view camera until the skin surface completely fills the viewport

Try to have bright and dark skin tones in your view.

Launch the script

Unless you did it previously, use the "Select reference image" button to select your reference skin-tone image

Note that this image should contain only skin tones.

If for example there was a green earring in your reference image youu could end up with green skin !

Once that's done, click the "fix" button and watch the script make extra efforts to make the skin color match the reference image skin

If the script misses the target you can try one of the following

- adjust the scene lighting, avoid using tinted lights

- adjust the mcjskinlikethis Diffuse color setting to something darker or lighter

- turn off the skin's specular ( glossy shiny ) effect

- adjust mcjskinlikethis's ambient strength to something higher or lower

- if your surface has an image map applied to it and this image is very dark, mcjskinlikethis's will have trouble making it bright white

Example of reference images i used succesfully

What the script does, i mean, really

the script will make up to 40 ( but often less ) tiny ( 256x256 ) software or hardware renders

until your rendered material looks like the one in the reference photo

what it does actually is to

- find pixels with the median lightness in the reference image

- notes the average color of those pixels,

- then finds a median-lightness pixel in your rendered image

- notes its location.

- tweaks of your surface diffuse strength

- renders

- it does up to 10 tweak/render cycles until the rendered pixel lightness is the same as the reference image pixels

- for the red, green and blue components of the diffuse color, it does up to 10 tweak/render cycles until the color is just right
