I am trying to fade out an object using an animation via UI button click. Color changes before it even starts

Hi everyone,

I am trying to change the material of a 3d object with an animation for an AR app with the Wikitude SDK.

The animation should only play after I click on the Button from the UI. When I click on the button the animation starts playing as it should be, with the material fading away.

The animation should only be accesible after I click on the UI Button's On Click() function.

However as soon as the object is visible its red material turns into grey. It is only after I click on the Button that the material turns into red as its a value goes to 0.

Is there a way to not lose the a value when the object is visible, or should I use a C# script with coroutines instead?

Thanks in advance :)
