SUMMARY:Head in the Clouds
DESCRIPTION:Kaylee Tian Lin Tan (Ringling College of Art & Design)\n\nIn t
 he production of my short film, I faced the challenge of simulating and re
 ndering clouds, despite having no prior experience in this area. The succe
 ss of my film depended on the appealing depiction of clouds, which played 
 a central and pivotal role in the storytelling. To tackle this challenge, 
 I conducted extensive online research, leading me to discover Houdini, a r
 enowned program for cloud rendering.\n\nDuring my summer internship as a C
 G Generalist at Hornet, I participated in Houdini office hours, where I ga
 ined crucial insights into Houdini and the complexities of volumetric node
 s (VDP). These insights proved invaluable in my quest to create clouds tha
 t balanced realism and stylization. I aimed to control the clouds' shapes 
 while imbuing them with fluffy, realistic textures.\n\nInspired by a paint
 ing 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 mak
 e the clouds irresistibly charming, drawing both the film's protagonist an
 d the audience into the ethereal cloud world, away from the mundane classr
 oom.\n\nTo achieve this, I constructed the cloud geometry base in Maya and
  Zbrush, providing greater control over their form. After finalizing the c
 loud shapes and its placement in the layout phase, I transferred the geome
 try to Houdini, implementing the node trees I had designed during my resea
 rch. 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 the clouds. I then composited th
 em with sky matte paintings in Nuke, creating depth and visual impact in m
 y shots. This innovative approach to simulating and rendering clouds not o
 nly transformed my short film but also reflected my dedication to achievin
 g a high level of visual storytelling.\n\nRegistration Category: Full Acce
