Multiply and add blending

(Position 6)

TechTest Room showing 2 Models with different blendings

Blending by multiplication and adding is used for some special effects.
TechTest Model using Multiply-Blending

Multiply mode darkens the background behind model. Note that the left object in the room (multiplication) is barely visible when you enter the room. That is because it darkens the background and is therefore best viewed on bright background. Approach from a different angle to observe it better.
TechTest Model using Add-Blending

Add mode brightens the background behind model. The right object is rendered by add-blending.
