DrTAD Blender Tutorial Animation Basics - Transforming 3D geometry with shape keys
1 like197 views
This document is a tutorial on the basics of animation in Blender, focusing on transforming 3D geometry using shape keys. It explains the two types of shape keys (relative and absolute), their applications, and provides a step-by-step workflow for animating objects. The tutorial includes visual aids and references to additional resources for Blender software.

- 3. 2018 DrTAD 3 Blender Animation - Shape Keys » Introduction Shape Keys are used to animate deform objects into new shapes. They can be applied on objects with vertices like Mesh, Curve, Surface, Lattice. There are two types of Shape Keys: ●Relative. Which are relative to the Basis or selected shape key. They are mainly used as, for limb joints, muscles, or Facial Animation. ●Absolute. Which are relative to the previous and next shape key. They are mainly used to deform the objects into different shapes over time. The shape key data, the deformation of the object’s vertices, is usually modified in the 3D View by selecting a shape key, then moving the object vertices to a new position. ●https://docs.blender.org/manual/en/dev/animation/shape_keys/introduction.html

They are mainly used to deform the object into different shapes over time. ●Reset Timing (clock icon). Reset the timing for absolute shape keys. ●Interpolation. This controls the interpolation between shape keys. Linear, Cardinal, Catmull-Rom, B- Spline ●The red line represents interpolated values between keys (black dots). ●Evaluation Time. This is used to control the shape key influence. https://docs.blender.org/manual/en/dev/animation/shape_keys/shape_keys_panel.htmll

In Object Mode, add a new shape keys via the Shape Key panel with the + button. 2. “Basis” is the rest shape. “Key 1”, “Key 2”, etc. will be the new shapes. 3. Switch to Edit Mode, select “Key 1” in the Shape Key panel. 4. Deform mesh as you want (do not remove or add vertices). 5. Select “Key 2”, the mesh will be changed to the rest shape. 6. Transform “Key 2” and keep going for other shape keys. 7. Switch back to Object Mode. 8. Set the Value for “Key 1”, “Key 2”, etc. to see the transformation between the shape keys. ● In the figure below, from left to right shows: “Basis”, “Key 1”, “Key 2” and mix (“Key 1” 1.0 and “Key 2” 0.8) shape keys in Object Mode. ●https://docs.blender.org/manual/en/dev/animation/shape_keys/workflow.html#relative-shape-keys ●https://docs.blender.org/manual/en/dev/animation/shape_keys/shape_keys_panel.html#settings
