Hello,
I was wondering if we can use textures with transpariencies or turning down the alpha channel in Unity shaders to create an transparency effect with Vuforia for Unity. I have tried fading out an object with a push of a button by turning down the alpha channel, but the object just disappeared.
Thanks in advance!
I am trying to use custom alpha shader for movie texture on unity. I 've used this shader for movie texture on a plane, this works when i publishing for windows. But when i tried to use this method on videoplayback sample project and when i changed video plane's materail shader to my custom shader. Video just disappeared when marker detected.
What is the problem ? How can i use my shader to videoplayback ?
anyone help me ?
Yes, though to adjust apha procedurally your shader will need to support an alpha channel.
See: http://answers.unity3d.com/questions/60453/fading-out-using-rendermaterialcolora-doesnt-work.html
Also see Related Questions to the right of that page. There are various approaches to creating fade effects, using both stock and custom shaders.
Have you confirmed whether your shader is working for the Unity movie texture on you mobile device?
