Before importing a 3D object, you must consider the scale factor to use. You can calculate the appropriate scale factor for a 3D model by comparing the measuring units used by Storyboard Pro to the ones used by your 3D modeling software.
This can be done by using Storyboard Pro's world grid. The world grid displays a grid over your drawing layers or 3D models using Storyboard Pro's standard measuring unit but, unlike the 12 Field Grid, uses the same proportions for horizontal and vertical distances, like 3D modeling software do. By laying this grid over a 3D object that is exaclty 1 unit in size in your 3D modeling software, you can compare the units used in your 3D modeling software to the units used in Storyboard Pro.
- In your 3D modeling software, create a cube that is 1 cubed unit in size (a cube that is 1 unit in width, 1 unit in height and 1 unit in depth).
- Export the model from into one of the formats supported by Storyboard Pro:
- Filmbox (.fbx)
- 3DS Max (.3ds)
- Wavefront OBJ (.obj)
- Allembic (.abc)
- Collada (.dae)
The cube appears in the center of the stage.
The default grid (the 12 Field Grid) displays over the 3D model in the Stage view.
The 12 Field Grid is replaced by the World Grid in the Stage and Camera views.
Once you get the cube's size to be 1,1,1 in Storyboard Pro's coordinates system, you can use the scaling factor you applied to this cube onto your other 3D models to make their coordinates systems match Storyboard Pro's coordinates system as well.
