What is the best BRDF model to use for ice? Is this a combination of reflection/refraction similar to the glass we implemented in the project?

The best BRDF model for ice is typically the Bidirectional Reflectance Distribution Function that combines both reflection and refraction, similar to glass. The Fresnel equations can be used to calculate the ratio of reflection and refraction at the ice surface. Additionally, incorporating subsurface scattering, which accounts for light penetration and scattering within the ice, can provide more realistic rendering results for ice materials in your project.

It might be a really cool thing to try putting the ice cubes in a glass of water and render the scene. That would produce a lot of compounding of refraction effects.

What is something that needs to be careful about while rendering the ice cubes?

This ice cube looks really nice, and I was wondering how the subsurface scatter model BRDF created the darker contents of the ice cube, if the light is simply refracted away from the camera.

This is really "cool". Are the darker areas a reflection of something?

that is so realistic

The black spots are black reflections from the object. If you want to get rid of it, you can increase the glossy rays and transmission rays.

These cubes look super great! I'm really impressed by the transparent effects and shadows in this image!
