Introduction to Expressions Before we really focus on Expressions, we should talk a little about relationships in After Effects in general.
As far as I know, there are five main ways to establish relationships between elements in After Effects: Brute Force: you simply keyframe things in a way that makes them look like they’re related, even though there’s no essential connection between them. This is perhaps the most common kind of relationship, and is extremely flexible, but can be tedious to set up and to modify later. Pre-composing: You can place a number of layers together in one comp, and then use that comp as a layer in a second comp.
Parenting: New to After Effects 5.0, Parenting lets you establish hierarchical relationships without pre-composing. Motion Math: Like Expressions, Motion Math is a simple programming environment within After Effects. Expressions: Expressions are similar to Motion Math, but maintain ‘live’ relationships.

Bonjour à tous, ça fait un bail, je vous l'accorde, mais comme je n'avais pas écrit de nouvelles expressions, je n'allais pas venir et raconter rien du tout.
Quand j'ai un problème technique dans After Effect, je cherche une solution, et quand la solution contient des expressions, ça vient logiquement s'échouer ici.C'est le cas aujourd'hui, j'ai essayé de corriger une lacune du plugin Lux de Trapcode. Ce plugin relavement connu est très pratique, puisqu'il vous permet de simuler un éclairage volumétrique, à savoir que la lumière soit filtrée par les particules dans l'air.
Vous trouverez tous les renseignements ici :Trapcode Lux Peut être existe-il d'autres éditeurs qui proposent un effet équivalent, mais je n'en connais pas d'autre.En général, j'essaye d'éviter de parler de plugin, car ça ne concerne pas tout le monde, mais celui ci est assez connu.Venons en au fait :Le "défaut" de Lux (qui sera je l'espère corrigé dans un théorique 2.0 ?....)
