Texture Swap Animator from wiki.unity3d does not execute on Unity play

Hello to all. I have tried to use the Texture Swap Animator script from wiki.unity3d, (see here) and it was working ok, both on Unity3d (free) play, or on Android testing device.

Suddently the script stoped exucuting in my project. I have tried it on a new scene, on a new GameObject, still no good at all.
What is more, whatever script I have tried in the same project in Unity3d (free) for texture swapping as animation, I still get no response at all.

Strange thing is, that on starting a new project and a new scene, the script works o.k. on every GameObject that it is attached to.

Furthermore, I’ve tried to copy the working attributes of the new project GameObject to my previous project settings, but it didn’t work out.

Is there a bug in Unity3d (free) or something else being broken in the installation and it is not working as before? Has anyone came uppon the same problem and what might be a working solution?

Need to have a texture animated in my initial desinged project. Can’t afford to start over a new project, from scratch, to make this script work again cause it is almost a 2 months work.

Thank you all in advance for your answers.

Do you have any error messages in the console? Did you accidentally deactivate the game object or the script?

Hello @Dantus. No I have not deactivated the game object or the script. I’m new to Unity, but I know how to attach and use scripts on game objects.
I have posted the same question at unity scripting forum, and I got some responce, but did not helped me to solve things out.

Take a look if you please:

Also I need to mention that I’m using Unity3d (free) with the NyARtoolkit plugin, if this is of any help to you :

I still cannot figure out, why the script is funtional on a new game object in a new project and no texture swaping script works on my initial project.

Please don’t waste our time by creating several threads with the same topic!
