Project #2: Photo Reference


These are a few of the reference photos we took as a group that I am considering for Project #2. We tried to create shots that allowed for back lighting, a lower camera, and hopefully, some interesting details to refract.

Project #2: Initial Tests

These were really quick shader development test renders, using the lighting set up from Project #1 and the Stanford Buddha and Stanford Lucy models.

Shot #1: Lucy Angel Statue and Buddha statue for comparison


Shot #2 : Shader development tests

Here I was trying to achieve the same light purple tone as the outer surface of my rock.


Shot #3: Shader Development Tests, Interior and Exterior Shaders

For this test, I duplicated the sphere, scaled it down, and applied a new shader to it so that I could start to achieve the idea of geometry within the sphere.


Shot #4: Refraction values on initial shader

Index of Refraction is set to 1.54, roughly the equivalent of quartz. Most polished/tumbled rocks from museums are quartz or a similar material.

I also found with my current lighting set up that the lighter the refraction color was, the more accurate my overall shader seemed to look. Darker refraction colors ended up rendering way too dark and it was hard to capture a look of transparency.


Project #1 Summary

Final Render for Class 6:



  • Ambient Occlusion in Nuke — worked on this afternoon and was able to fix node tree.
  • Environment shadow wrap — shadows don’t seem to line up with scene and once included in the Nuke node tree, seem to lighten or disappear altogether.
  • Pre-multiplication and artifact problems
  • Ground plane geometry — I worked on modeling a similar ground plane, but it doesn’t match perfectly.
  • A ground plane with a surface shader was accidentally left in the keylight layer, altering the shadow pattern and causing the objects to become too bright underneath.
  • Noise

Project #1: Progress, First AOVs

This was my first attempt at separating my test renders into different AOVs. For these shots, I also included my soccer ball .obj file so that I could start to see how the object would look in the scene.

The original photo image is projected on the ground plane for these test renders.
