SUMMARY:Head in the Clouds
DESCRIPTION:Computer Animation Festival\n\nKaylee Tian Lin Tan (Ringling C
 ollege of Art & Design)\n\nIn the production of my short film, I faced the
  challenge of simulating and rendering clouds, despite having no prior exp
 erience in this area. The success of my film depended on the appealing dep
 iction of clouds, which played a central and pivotal role in the storytell
 ing. To tackle this challenge, I conducted extensive online research, lead
 ing me to discover Houdini, a renowned program for cloud rendering.\n\nDur
 ing my summer internship as a CG Generalist at Hornet, I participated in H
 oudini office hours, where I gained crucial insights into Houdini and the 
 complexities of volumetric nodes (VDP). These insights proved invaluable i
 n my quest to create clouds that balanced realism and stylization. I aimed
  to control the clouds' shapes while imbuing them with fluffy, realistic t
 extures.\n\nInspired by a painting of pink clouds from the New York Public
  Library, I established a color palette to make the clouds resemble cotton
  candy. It was essential to make the clouds irresistibly charming, drawing
  both the film's protagonist and the audience into the ethereal cloud worl
 d, away from the mundane classroom.\n\nTo achieve this, I constructed the 
 cloud geometry base in Maya and Zbrush, providing greater control over the
 ir form. After finalizing the cloud shapes and its placement in the layout
  phase, I transferred the geometry to Houdini, implementing the node trees
  I had designed during my research. These cloud models were then exported 
 as alembic caches and returned to Maya for rendering.\n\nFor complex shots
  with dynamic camera movements, I used Arnold for lighting and rendering t
 he clouds. I then composited them with sky matte paintings in Nuke, creati
 ng depth and visual impact in my shots. This innovative approach to simula
 ting and rendering clouds not only transformed my short film but also refl
 ected my dedication to achieving a high level of visual storytelling.\n\nR
