For general information about Attributes : Effect interface
Above: Example of attributes in 1. Effect Control (After Effects), 2. Timeline (After Effect), 3. Effect Interface (PopcornFX Editor).
Due to SDK limitation from After Effects, attributes are created automatically as separated effects. Those are instantiated when selecting an .pkfx for an PopcornFX emitter effect
Be aware that any key frames on attributes will be lost when selecting another effect.
You should not:
- Copy/Paste, delete, rename those by hand.
