    hi all... Ok, we played around with glass, finding out that the refraction for glass was somewhere around 1.517....

    now, how about adding some water to those cups... just what is the refraction levels, as well as any other setting involved within CE or C4D, in order to make nice water... and if we took this one step further, and created a whole bunch of tiny spheres around the edges of the water line etc, then would these be the same values?

    Water settings = ?
    bubble settings = ?


    I hope that we can find these answers out

    ok, Just recieved info that water refraction is 1.33...

    anybody have any thoughts on this?

    anybody care to test this setting out by placing an object within a glass mug/cup and doing some renders ?

    Hi Gidget,

    I'm not really happy with the lighting in this, but I've spent hours trying to get it better. One cup without water and one with.

    Yeah Soquili, know what you mean. I've been playing with this for hour too and just can't seem to get it right. Refraction index is set at 1.33.

    Here is my attempt. Used the glass material, from earlier post. Used 1.33 for Refraction on water. No bubbles yet.

    I'm a stubborn old f**t. Played around for a couple more hours. Added an array of lights and put the whole thing inside a huge reflective sphere. Still didn't get anything close to what I had envisioned. Finally enable the phong tag on the glass and water and limited the angle to 80 degrees. Also offset the checkerboard material on the floor slightly in the +X direction. Glass is refractive index of 1.517 and water at 1.33.

    Very nice work Fossman and Randy. Guess we have to have a go at bubbles now

    Here's mine, I Rendered in Bryce. The Bryce materials editor uses a slightly different set of numeric values, but I believe its about the same end result, Eg. refraction value is 133 instead of 1.33, bumpy colored glass mat. refraction = 152.

    Fun
