Blender Alien Creature Tutorial Part 3: Alien mouth Tentacles ... and Shape Key Animation in blender
We make some Alien mouthparts for our creature. The small tentacles will use shape key animation and the two larger ones will be rigged when we rig the creature.
Cycles is Blender’s ray-tracing production render engine.
To use Cycles, it must be set as the active render engine in the top header. Once that is done, interactive rendering can be started by setting a 3D View editor to draw mode Rendered using Shift-Z. The render will keep updating as modifications are done, such as changing a material color, changing a lamp’s intensity or moving objects around.
