What is stopping (iRay) shaders from applying to objects?

Object: "SYCGLI Liquid Short" from https://www.daz3d.com/sy-morphing-cup-and-glass-liquids-for-iray

I try to apply -- from the same product -- the shader "SYCGLI Milk Shader"

I have double-clicked, I have dragged and selected 'Apply to SYCGLI Liquid Short', and the liquid does not change colour.

[This applies to the other shaders in the collection as well.]

I have also tried applying "generic iRay shaders" to some surfaces and they don't take, either.

To add to the aggravation, I can add the qualifier that "sometimes it works", and I have NO damned idea what I am doing right/wrong here.  Halp!

    When you say you apply, you do select the object, go to the surface tab and select the surface and apply, correct rather than just selecting the object and trying to apply the shader?

    ...do I always have to jump thru that??  I have found that sometimes I have to, sometimes I do NOT have to do that.
    The inconsistency on this baffles me.

    A materials preset has a list of surfaces that it should aply to, potentially different settings for each. A shader preset has a set of proeprties that will (by default) be applied to al selected surfaces on all selected objects. The Surface Selection tool allows you to use a single click in the scene to select both.

    I must be losing my mind*.  nemesis10, thank you.  I'm still baffled.

    It is because people are sloppy.  Traditionally in Daz Studio, a shader is applied to a specific surface and a material preset does all the applying to multiple surfaces for you.  Each has its own advantages: shaders are great when you want to do something specific such as give your character teeth of solid gold for example; you have access to all of the shaders out there with the limit being your imagination. You want brick teath or diamond teeth, easy!  Materials are generally used by vendors for complex figures and objects such as characters and wardrobe sets. You don't want to always have to apply the button color to each button. If you want to do a special effect, though, a shader will help you.  For example, you apply that nifty material preset to a given shirt but want it to look like it is soaked, you can apply a shader such as https://www.daz3d.com/iray-wet--dry-fabrics and voila!

    Thank you both for helping un-muddy the fog.  I am grateful!
