are facing the opposite direction on the backside. Thus, when you revolve around the back, you
see the second image plane that has its normals facing the opposite way.
Fusion does exactly the same thing as 3D applications when you make a surface two sided.
The confusion about what two-sided lighting does arises because Fusion does not cull
backfacing polygons by default. If you revolve around a one-sided plane in Fusion, you still see
it from the backside (but you are seeing the frontside bits duplicated through to the backside as
if it were transparent). Making the plane two sided effectively adds a second set of normals to
the backside of the plane.
Note that this can become rather confusing once you make the surface transparent, as the
same rules still apply and produce a result that is counterintuitive. If you view from the frontside
a transparent two-sided surface illuminated from the backside, it looks unlit.
Material ID
This control is used to set the numeric identifier assigned to this material. The Material ID is an
integer number that is rendered into the MatID auxiliary channel of the rendered image when
the Material ID option is enabled in the Renderer 3D tool. For more information, see Chapter 76,
“3D Compositing Basic” in the DaVinci Resolve manual or Chapter 25 in the Fusion
Studio manual.
Common Transform Tab
Many tools in the 3D category include a Transform tab used to position, rotate, and scale the
object in 3D space.
Translation
X, Y, Z Offset
These controls can be used to position the 3D element.
