How to make hair texture wet?

James

I don't need the shape of wet hair.
Or wet hair product.
I just need how to make hair texture looks wet.
Or maybe wet hair shadder if exist.

It depends on the hair's Shader... It can vary which parameters are creating the "Shiny" look the hair has, which is what you want to crank up to move toward a wet look.

 

With the hair selected, in the Surfaces Tab (pay attention to which Surfaces of the Hair are selected in the Surfaces Tab, you may need to expand the hierarchy on the left and use Ctrl to select the surfaces you want and leave out ones like a Skull Cap, etc), then in the parameter list to the right, look for:

 

Glossy Layered Weight

Glossy Roughness

 

And/or

 

Top Coat Weight

Top Coat Roughness

 

Usually one of these sets is controlling the "Shininess" of the hair (either can just as easily be used to refine the color of the hair instead). Usually you would want the one you're cranking up to look shiny and wet, to have full value White in it's "Color Selection Bar".

 

Generally...

 

Weight = How much shine (from 0.0 to 1.0) For wet, consider closer to 1.0

Roughness = How "hard" of a shine (from 0.0 to 1.0, with 1.0 being dull and 0.25 being extremely "hard/shiny/wet".

 

If Glossy Layered is what's controlling the "Shine" on a particular hair, then also look at Glossy Reflectivity (0.0 to 1.0). This controls how reflective the Gloss is, and if I'm going for wet, I'd probably use closer to 1.0.

 

One other thing to consider with lighter colored hair... When light blonde hair is wet, for instance, it looks quite a bit darker than when it's dry, so consider looking at the Base Color, click in the Color Selection bar and try dragging the brightness slider down little bits at a time and checking to see if it's helping, etc.

 

I'm sure there's more ways to attack it and possibly more well informed info about how to set the Parameters I mentioned, even. Try playing around and feel free to keep this Convo going if you can't get what you're after!

Thanks for this, Phatmartino!

Wonderful instructions there!

Yes, my default starting point when she's walking in the rain is:

Glossy Roughness: 0.25

Glossy Reflectivity: 0.75

and it's usually just what I want. Sometimes just the 0.25 Roughness is enough, leaving the Reflectivity alone.

 

If you play with this and still want it looking more wet, try this:

• Select the Hair
• Create > New Geometry Shell
• Select the new shell and, in the properties tab select Shell
• uncheck anything you don't want the new shell to affect
• In the Surfaces tab, Shift or Ctrl + Select all of the materials you want to use
• Go to Content Library > Shader Presets > Iray > Daz Uber and double-click the first one - Daz Iray Uber
• Then scroll down in that same category and pick either a glass or water shader and try it out.

Now we can go back to the properties tab with the new shell selected and set how far away it stays from the mesh it's attached to.

To me,  'Shinny hair' or 'Glossy hair' is totally different from 'Wet hair'.  A Wet hair should be with 'Wet hair mesh'...
