For a pic I made the other day I needed freckled skin. So I tried to hook up a spots node - with .. semi-acceptable result.

But where should that noce preferably go? If at all? Is there a nice and easy way of making freckled skin with EZSkin2?

I think I read some thread were Snarrly said he needed a royalty free freckle map...I could be wrong.

This is BB's solution back in 2007.  Of course, this would require modifying the existing EZSkin node structure to work.

The 2007 solution still applies. You modulate the color map - so where it goes now, the modulated color goes. That would mean adding those nodes between the color map and the Scatter.

Aha! Thanks! 

And thanks for explaining where the new nodes should go :) Experiment time :D

I've managed.. somewhat.. but they're still very faint.

I think it's the Comp node (which I'm not sure exactly what does) that makes it harder. I tried at first with the pale yellow, but then they were completely invisible. With a darker colour in the Blender they're at least somewhat visible...

So.. any ideas for improvement?

Hi TrekkieGrrrl... sorry, but I'm finding it hard to see exactly where you're plugging that spots node in there... is it just being blended with the color map node, prior to the rest of the EZSkin shader, that is then processing that color map?

Ah... ok... I see what is connected where now, sorry.

How much darker do you want the freckles? I think they look okay in the preview render?

What does the blender node preview look like? That'll show the blend, no?

I never used the second blender node :) But thanks for the warning/explanation :)

To me, the freckles in my example looks more like an overall mottled ook. When I look at my own freckles (which I WISH I didn't have) they're much more prominent.. at least to me L

You have the blending value at .7 - that reduces the strength of the freckle. Set it to 1.

I wonder if modulating the yellow chip to a darker tint may make the freckles more prominent.  Worth a try.  

Personally I think freckles look great. Which is just as well... my missus is ultra freckled after all the sun we had this annum...

I really like the texture you've got there TreckieGrrrl... a bit darker would be good...

Will have to try this out later... been tinkering a little with control maps to modulate skin textures for Roxie... mostly, so far, regards trying to achieve some pore and surface capilliary detail effects... that I want to work close up and also from full body view, etc... without needing super huge color / bump / disp maps... just been trying to get to grips with 3d painting in Photoshop for the control maps... but not got a lot of time just now...

...freckles and moles are also on my agenda there... good to read this thread...

Also... would a color_math multiply node be a valid alternative to that blender node?

Yes but then you'd lose the strength knob.

Wait I just re-evaluated what you asked. You're suggesting multiply instead of blend? No that would be bad. You would be doing

skin * freckled_skin

instead of

(1-k) * skin + k * freckled_skin

A Color_Math Add would be a valid alternative.

Value_1 * skin + Value_2 * freckled_skin

However, this doesn't buy you anything.

Ah, okay... I see. Thanks BB.

What about color_math darken?

Are we still looking for how to make darker freckles? As I wrote above - set the blending value to 1, so that 100% of the freckled_skin is being used instead of 70% blended with 30% normal skin.

There is nothing wrong with blender - it is capable of giving you 100% of the Value_2. We have not yet seen the outcome of doing that.

Once you do that, you have the further option of making the freckle color (spots node) darker.

Once we get there, I suspect what is going on is

• sheen - too much specular reflection washing out the diffuse (scatter) coloring

or

• scatter diffusion making the freckles less distinct, in which case the solution is easy - adjust the scatter node so it isn't blurring the freckles so much

Thanks for the inpputs. I will try some of the things mentioned once my current (completely different) render finishes. Sometimes tomorrow judging from the current speed of it L 
Heh the worst thing about Poser being ABLE to finally use DOF ext without choking is.. I tend to use it. And while it LOOKS great.. it also multiplies render times.. sometimes ad absurdum... but well.. it looks nice L
