Ive searched all over and not really sure how to get this type of hair reflection or glow or whatever its called. https://78.media.tumblr.com/ecd51cff3ef7b197e934b9f5790b975f/tumblr_inline_p9b5avbeHu1s20gcb_500.gif

Not sure if this gif in the link will show up, but Im trying to get that effect in blue. Ive ringed my model with blue spotlights and it never works. Ive tried all kinds of different lights and nothing is working. I made the hair emissive in iray and it was just glowing hair and not what I was after.  I got carrara because someone said its the thing to have only to find I have no way or moving a scene from there to daz studio and cararra is no longer in development so Im not sure why its sill up for sale. Seems I wasted my money on it.

Im not sure what else to do. In the attached pick, is what Im after as well, just in blue light.

    I don't think you want to ring you figure in spotlights, you just want one really bright, really focused colored light pointing down on the model.It will probably be as close to the figures as you can get it without is showing up in the render. You don't want the hair to be emissive, but translucent. There is probably also going to need to be some haze or particles in the scene to get the glow just right, or you could try messing with the bloom filter.

    If you just Carrara in the last 30 days, you can put in a help ticket and get a refund.

    Hope that helps, or at least gives you a starting point.

    In real life this effect is created by light shining from the back at the head of a person.

    The light rays pass trough the very thin hair strands and therefore they are fully colored by the light.

    In computer graphics the key to recreate this effect are mostly three things:

    - - -

    - Use fiber mesh hair geometry with thin individual hair strands

    Example:

    https://www.daz3d.com/charlie-hair-for-genesis-2-female-s

    There are a few "traditional" hair styles with a lot of transparency maps and layers that you can tweak to get a similar look.

    But if you are going for realistic light effects you may want to actually use hair with geometry based hair strands.

    - - -

    - Fine tune the hair material settings to use the proper subsurface scattering effects so the light rays can pass through the hair strands

    - - -

    - place a light emitter behind the figure and experiment with the placement until you see the effect you want.

    Since this is the DAZ Studio forum just as side note:

    I am not famiilar with the default render engine of Carrara.

    However, there is an OctaneRender plugin for Carrara.

    I currently do not know

    - if there will be a free version of the plugin for the next OctaneRender 4 version

    or

    - if it will be included in a 20$ per month subscription.

    -> You may want to ask around in the Carrara forum

    on DAZ3D

    or Otoy
