Settings contain many configuration options for UPV.

Project tree configuration

You can toggle between tree view and tree bar:

Tree view places the project tree in the menu on the right.
Breadcrumb tree places the project tree on top of the main window. You can choose attributes to automatically generate a different project tree.
Each attribute defines a level in your project tree.

Example: Material, Date created will give you all objects with the same creation dates for each material.

Additional settings

Additional settings open a new tab containing many options to finetune UPV usage.


Shows/hides selected objects

Attribute options

Empty attributes shows/hides attributes with no values.

Configure priority attributes decides which attributes and in what order they are shown when hovering an object.

Preview attribute limit decides how many attributes can be previewed when hovering over a 3D object.

Limit for automatic labelling decides how many labels can be shown at once in the 3D view.


Choose the unit to be displayed when measuring or adding objects.

This does not apply to the attribute’s information.

Toggle options

(navigation and drawings)

Common views cube shows/hides the navigation cube in the upper right corner in the 3D view.

Minimap shows/Hides the minimap in the bottom right corner of the 3D view.

2-sided ISO perspective chooses the side the 2-sided ISOs will face.

Use Common Views XYZ-Mode changes the view cubes faces from compass directions (North for North, S for south and so on) to cartesian display XYZ.

360° Panorama shows/hides the red spheres indicating panorama positions.

Colour ramp creates a hight-map for the 3D model and colours objects accordingly.

Use old camera rotation behaviour changes the camera back to older UPV versions, rotating around the centre of the screen instead of an object.

Hide movement indicators hides the spheres showing the point the camera is rotating around while rotating.


Change the colours/patterns of the specified objects.

Day and night cycle

UPV implements a day/night cycle with actual shadow simulation. Decide what time the simulation should start at.

The time multiplier increases the flow of time in the 3D view.

Performance options

Advanced users can adapt cache size, maximum number of triangles and maximum camera range to fit their needs.

Triangles limit: Limits the maximum amount of triangles the system can load.
Render quality level: Low: 30 FPS. Medium: 30 FPS, Ambient occlusion. High: 60 FPS, Ambinent occlusion, Shadows.
Memory mesh cache size (triangles): Limits the model caching size by accessible triangles.
Memory model cache size (bytes): Limits the model caching size by accessible bytes.
PDF projection max render jobs: This setting refers to the rendering of PDFs in the context of Zooming in and out. Limits the number of parallel rendering jobs/panels.

UI options

Adapt the scale of the user interface from 0.6 to 2.0 and change the attribute font size from 2 to 6.

Your changes to additional settings instantly become effective, but you have to save them in a configuration file if you want to reuse them after closing the UniversalPlantViewer.
