This is the diffuse pass.
This pass is used to define the colors in the scene. As you can see I made a Dr. Pepper bottle with paint splatter all over it. The glass however does not show up. Strange, right? Well I will explain why that is in the next few passes!
This is the indirect pass.
This indirect pass shows how the different light bounces off itself to make the colors change and become more vibrant. This pass also is how the caustics (the red light on the ground) comes through. Still no glass though.
This is the reflection pass.
This is the reflection pass that is showing the glass now! Because glass does not have a color is relies on all the reflects and refractions in order to have any kind of form. Without this pass we wouldn't have the form on the bottle.
This is the refraction pass.
This is the refraction pass. Without this pass you wouldn't be able to see how the light bends when it comes in contact with the bottle and the liquid inside.
Lastly this is the specular pass.
This pass is used to help make the highlights come through more. Its an important pass to make the bottle seem more real.
Final product!
This is what it looks like when everything comes together! It was a lot of fun to make this bottle and see how it all came together. I will definitely be able to use this in the future for many many things. I cannot wait to see all the wonderful glass things I can make!
