How to render lifelike ice in Luxrender.

Start by making a cube and make it rounder and irregular, or download it, enough free models on the internet to be found.

Startup Daz Studio or Poser and setup your scene

Now add a Geometry shell in Daz Studio or make a copy in Poser and make it a little bit bigger than the original.

Open Reality and click first on the original ice cube and go to the opacity tab.
Click on the gear and put in a new image map choose one of my textures to use Ice-1 or Ice-2 picture.
No need to change the colors in the materials tab as the gray color is just fine.

Now click on the Geometry shell or copy and right click on the cube and make it a glass material.
Use the standard glass type and use in IOR the number 1,3335 or select in the presets liquids/Water: Frozen

You can give the glass textured shell a bump map and a displacement map if you make a frozen pont or river.
Now start to render in CPU- No acceleration as the accelerated modes gives to much noise and fireflies that will not solve.
Have a good old fashioned patients when it renders for hours, but believe me, it is worth the waiting and a good excuse to play a game or watch a movie.

Here the finished test render.


Here are the textures i have made
Download the pictures by right click on it and choose open in new tab then save image as

This texture gives sharp cracked ice with lot of turbulence in the frozen water

Ice-2 This texture gives a smoother inner cube with less turbulence in the frozen water

Aha! Thank you. Just in time for icicles in a Christmas render.
