Hello, i am totally new to the Babylon.js scripting framework. My first question is, how can i change the value of alpha for an material on klick event. samplematerial.alpha = 0.3; seems to be a float , however, there is also new BABYLON.Color3 and new BABYLON.Color4 which can be changed on actionmanager code. Color3 is RGB and Color4 is RGB Alpha. So how can i change the alpha value ? Should i use color4 ? Here is what i have so far : http://www.babylonjs-playground.com/#1ST0I Also, i can´t figure out which of this code seqments do what or how they are named like. Like this things that are inside "example". I have to begin somewhere so i hope my first question isn´t that bad. Greetings and thanks in Advance
