Workbench
Set Extension
24
June 2011
The
goal for this locked-off greenscreen VFX shot was to create photoreal
CG assets in Maya that extend the set behind the workbench. I also
wanted to enhance the character in the shot by removing his left
pinky and ring fingers, a result of his previous misdoings. A scar
tissue patch created in Photoshop was then tracked & warped
into place using Nuke.
In
Maya, I camera-projected the original plate footage onto some simple
geometry to create reflections on the CG assets. A few basic Maya
render passes including a lights ID pass allowed me to tweak the
CG elements in the Nuke comp, sitting them into the plate. Lens
characteristics were also applied to the CG elements using a z-depth
pass for camera depth of field and lens distortion profiled from
a grid photograph taken on my Canon 550D/T2i.
The
camera movement for the title section of this video was created
in Nuke's 3D environment using cards, a DisplaceGeo node on the
hand, an animated camera path and a bit of camera shake applied
to the output of the ScanlineRender node.
