Getting started

After you installed the Blender addon as described above you will find a new tab in the right hand sidebar of the 3D-Viewport. You can define a new shelf by clicking on "Add shelf". Now left click inside the 3D-View where you want your shelf to start, left click again to set the end point. Books will automatically be generated to fill the selected shelf. At any time the parameters of all shelfs can be adjusted by using the panels: "Properties", "Leaning", "Proportions" and "Details".



At the top of the "Properties" panel you will find settings affecting all books:

  • Scale: Allows to change the overall size of the books
  • Seed: Allows to generate different variations from the same settings
  • Alignment: Allows to align the books at the spine, fore edge or center
  • Material: Allows to assign a existing material to all books


In the "Leaning" panel you find settings to add books that have fallen over:

  • Lean Amount: Defines the overall number of leaning books. 1 means all books are leaning.
  • Lean Direction: Defines the direction in which books are leaning. 0 mean equally left and right.
  • Lean Angle: Define the average angle at which books are leaning.


The "Proportions" panels contains settings to change the overall shape of your books:

  • height: changes the height of your books.
  • depth: changes the depth of your books.
  • width: changes the width of your individual books.


The "Details" panel changes the smaller features of the generated books:

  • textblock-offset: changes the offset between cover size and textblock size
  • cover-thickness: changes the thickness of the books covers
  • spline-curl: changes how bulgy the back of the books are.
  • hinge-inset: changes the inset at the hinge
  • hinge-width: changes the width of the hinge
  • Add Subsurf-Modifier: adds a subdivision surface modifier to your books.
