OptionalintensityMultiplier on the cubemap IBL ambient + specular contribution.
Range [0, ∞). At 0 the cubemap contributes nothing even when
the active View.renderMode is in
IBLParams.renderModes.
Default value is 1.4 — a modest boost over the natural 1.0
level so RealisticRender's prefiltered-cubemap fill reads as
distinctly brighter than the analytical hemisphere fill in
NavigationRender / DetailedRender.
OptionalrenderWhich rendering modes in which to apply cubemap IBL.
Default value is [DetailedRender, RealisticRender].
Parameters for IBL.
