Shadow Correction
Enable Shadow Correction to prevent artefacts from appearing at the
edges of objects.
When rendering multi-passes with shadows switched on, slight artefacts such as bright lines may
appear at object edges due to antialiasing. To prevent these artefacts from appearing, enable this
option.
Straight (Unmultiply Alpha)
This option is only available if you have activated the “Alpha Channel” option in the Render Settings
“Save” tab. Whether or not you activate “Straight Alpha” does not play a role.
With the “Straight (Unmultiply Alpha)” (“Multi-Pass” tab) option you dene whether or not the
corresponding multi-passes should be “pre-multiplied” with reference to the alpha channel that is
saved.
Separate Lights
Use Separate Lights to choose which light sources have their own separate layers.
None
No separate layers.
All
Each light has separate layers.
