Look-deved shaders for the Machine.
lit the CG Machine in V-Ray.
Set up render layers and render elements for
compositing.
Integrated CGI into background plate.
Gundam F-91
•
•
•
•
Responsible: everything.
Software: Maya, V-Ray, Nuke, Mari, Mudbox,
PTGui Pro
• Integrated CG Gundam into the live-action
plate to create a war-zone type of shot in
moody sunset.
• Acquired HDRI on-set with Canon DSLR,
Sigma 8mm fisheye, Promote Control, and
Nodal Ninja pano head.
• Assembled HDR env. map in PTGui.
• Modeled the Gundam in Maya and laid out
UVs.
•
•
•
•
Sculpted details (bullet holes, deep scratches,
and random indentations) in Mudbox and
extracted normal and displacement maps.
Textured in Mari with some visits to
Photoshop.
Calibrated HDR lighting with reference gray
ball image shot on-set.
Created multi-layered metal shaders for finer
control of dirt, grime, and scratches in
textures.
Look-deved and lit the Gundam in VRay.
Rendered multi-channel EXRs with numerous
mattes for compositing.
Composited CGI, stock fx elements, and plate
in Nuke.
Kept Imaging pipeline consistent in linear
color space with 16-bit half-float EXR as
much as possible to preserve the lighting and
color information all the way to the final video
compression and web publishing.
Spatially-aware IBL set up
•
•
•
Responsible: R&D, custom Python scripts,
lighting, rendering
Software: Maya, V-Ray, Nuke, PTGui Pro,
HDR Shop
• Researched on the workflow to address the
static lighting typical IBL while a shot
features dynamic lighting conditions.
• Reconstructed set environment as lowpoly mockup geometries based on
photogrammetry.
• Acquired HDR environment map at
multiple key positions on-set.

•
Textured mock-up geometries by
projecting HDR maps in Nuke from the
positions of the CG character.
Set up Nuke script with animated cubiccam rig to re-photograph animated HDR
environment maps from the POV of the
CG character.
Created a CG light stage in Maya and
rendered a set of light-stage basis images
of the CG head with V-Ray.
Calibrated basis images based on the
concept described in the paper A Lighting
Reproduction Approach to Live-Action
Compositing (Debevec et al., 2002).
Created python scripts to calculate
weighted average of basis images to
interactively approximate the lighting
result the re-photographed environment
map provides.
capable of blocking out the shot lighting
directly in Nuke with HDR light cookies
and lighting information acquired on-set.
