RIB Wrangling

A RenderMan RIB-based procedural shading and lighting study
focused on Halloween-themed teapot decoration, texture projection, presence masking, and organized scene construction.

  • RIB scene assembly, shader setup, and RenderMan lighting
  • Texture mapping problem solving through presence masking
  • Technical breakdown, source RIB files, and before/after comparison

Problem and Solution

Sphere Texture Mapping

I initially used spheres for the plates, but the textures did not map correctly to the original images. Although PxrProjector could potentially solve the issue, I did not have enough time to fully implement it in RIB. Instead, I switched to square polygons and used presence masking to create rounded plate shapes.
