(Main) Group

Last updated 29 May 2023

Groups are mainly used to organize output rendering. The sequencers, assets and outputs are rendered per group. For single screen projection projects or for multiple display projects, no sub groups need to be created.

Properties (Group)

Name

Editable Name of group

User Interface Settings

(Main group only)

Global Scale

Scale projector, ground grid & markers in GUI

Frames per Second

Defines the FPS of local and Performance Mode GUI

Show Grid

Shows grid on ground plain

Grid Orientation

Defines the orientation of the ground plain grid

Show Projector Field of Views

Show/Hide all projector field of views of projectors in group

Label font scaling

Scale labels in 3D view

Background Color

Set background color of 3D view

Performance

Performance Mode

Performance

Optimized for typical media playback

Simulation

Advanced mode including shadow calculation and compensation

Custom

Specify render steps to be done

Blending

Blending

Enable Blending

Enables blending of projectors in render group

Gamma

Gamma used for calculating the blend mask, brightness correction and black level correction.

The gamma value must match to the gamma value of the projector.

Blending Algorithm

Use Precomputed Blend Weight

Enable Debanding

Diffuses blendmask for 8 Bit

Brighness Correction

Brightness Correction

Disabled, Local (for individual projectors), Global (for all projectors as group)

Mechanical Blending

Enable Mechanical Blending Compensation

Enables option to adjust digital blending to work with mechanical masks. Can only be used with Calibrator.

Blacklevel Correction

Enable black level correction

Enables/disabled Black level Correction. Can only be used with Calibrator.

Threshold

Specifies the influence of the black level corrected image values. 1.0 means, full correction is applied. 0.0 means, no correction is applied.

This value is also accessible through the Scene::Properties node to allow to disable black level correction in certain scenes.

Note that any value between 0.0 and 1.0 might show some color shifts on screen with certain content.

Black Level image blur

Apply an Average or Gaussian blur on the black level correction image. This helps to remove noise in the correction image.

Enable Debanding

Diffuses black level correction mask for 8 Bit

Enable Color Correction

Allows to adjust colors and the general black level brightness (All). To reduce black level correction, adjust the All parameter.

Shadow

(Applies only in Simulation mode)

Reduce shadow texture resolution by 50%

Quater resolution for shadow (improves performance)

Enable shadow smoothing

Shoothes borders of shadow

Shadow extension

Adjusts shadow compensation

Transition area size

Adjusts shadow compensation

Sampling distance

Adjusts shadow compensation

Transition curve

Adjusts shadow compensation

Test Images

Test Image:
Single Color
White Bar Overlay - Horizontal
White Bar Overlay - Vertical
Periodic Flashes

Set test image on all surfaces of selected group

Output Settings

Enable Projector color filter

Colorizes output of projector with the color of projector in scene view. Especially useful for manual warping of blended projections.

Output filter:

None
Lanczos

Applies selected output filtering. Lanczos allows sharpening of image details.
