Someone can help me create or find a shader/material preset to obtain the effect of that image?
It's related to carrara but Carrara's presets doesn't work in DAZ Studio!

    For 3DL or Iray?

    3DLight... Sorry, I forgot to add that detail! *blushes*

    There is an Iray shader Glass-Solid-Frosted-Clear which comes with the Iray default shaders.

    The first image is a plane with the shader added and untouched. The second one I lowered the Glossy Roughness to .35.

    Looks good enough, but it's Iray... And I need it in 3DLight...
    I could try to convert it with that new Iray to 3DL conversion script but seems to not worl for me, I don't know if I'm doing something wrong with it!

    Yeah, the conversion script won't handle complex stuff with refraction/SSS/etc.

    And... huh. I don't see anything like 'refraction blur' from any of the normal 3DL shaders I have (US, US2, AoA SSS, plus normal). Weird.

    Seems an obvious lapse.

    This refraction blur sounds like the missing piece... I haven't mastered shaders yet, but I can follow instructions and learn...
    How can I set up a simple shader that activates that function?

  • Oso3DOso3D Posts: 15,009

    I have no idea if it even exists. You should check out the 3delight lab thread on Common (I don't have a link handy)

    I'll try there then... Thanks!

    You could try mapping the index of refelection with a noise map (or procedural). What I did once, a long tiem back, was increase the sample cone setting on the refraction brick (which meant stuff close to the glass was sharp and more distant stuff blurred), but I think that was DS3 and the bricks are somewhat changed in 4.

    I'll give it a try, thanks!

    The main problem is that the shader builder and similar systems aren't very user friendly!

    (almost spits out his drink)

    Yeah, that's... an understatement.
