Effects can be added to any Layer and will modify the Layers visual output
This guide provides an overview of how to apply, adjust, and manage effects in layers within Igloo Core Engine. Effects can significantly alter the visual output of layers, and when combined, they form an Effects Chain. The order of these effects in the chain is crucial in determining the final visual output.
Managing Effects
Adding an Effect: To add an effect to a layer, select the desired effect from the effects list. Multiple effects can be

Reordering Effects: Change the order of effects using the up/down arrow buttons. The order impacts the final visual output.
Effect Types
Each effect type serves a unique purpose.
Invert
Invert Inverts the layer in the X or Y axis, offering a mirrored effect.
Cubemap to Equirectangular
Converts between the selected Cubemap Format and Equirectangular.
True Perspective
The True Perspective effect extracts the corrected perspective view from a 360 Layer, while accounting for the geometry of a screen of arbitrary proportions (Cylinder, Immersive Room etc) that it is being displayed on. It can also adjust the perspective for different viewing locations. All in Realtime!
The Igloo Setup application is required for generating the True Perspective calibration files ICE.
Parameters of the True Perspective effect can be used to modify which region of the 360 content is displayed
Heading
Rotates the content Left and Right
Pitch
Rotates the content Up and Down
Direction
Sets the direction the content is Pitched in
Custom Head Position
When enabled a custom head position can be set for this layer.
When disabled the global head position is used, found in the General settings window. Config > General > Misc > True Perspective Head Position
...
Plane to Equirectangular
This effect transforms flat images into 360-degree equirectangular projections.
Usage:
Ideal for converting standard non-360 content or graphics into a 360-degree view.
Parameters:
Adjustment Settings: Customize how the flat image is projected onto the equirectangular format, including scaling and positioning adjustments.
Field of View: Control the extent of the scene captured in the projection.
Orientation Controls: Adjust the orientation of the image within the 360-degree space to achieve the desired perspective.
