This seems like a weird place to put this question, but it seems more appropriate than the others.

I attempt to do this once every three years or so, so I can never figure out how to do it again and its driving me crazy! What I want to do is have a model with a material applied and the attributes of that material change with time in an action. For example the object could change from blue to red, or become transparent. I want to control this through a applied material and not the models surfacing if that makes any sense. But I cannot see a way to do this.

Mark,
Animating a material is straightforward enough.

Once applied you'll want to look for the material's shortcut in the Choreography and simply animate it/change it over time.

I know this will seem too simple an answer but thats really all there is to it.
You might have to toggle 'show more than drivers' on. Thats the reddish folder looking icon you'll find under the resources shortcut.

The easiest way is using the gradient combiner my latest posting has a v13 project where I have a model go from invisible to an animated material

If you still need help I can might have time to post a simple tut this weekend

Thanks John,

I was trying to do it in an action and it turns out the material is hidden inside show more than drivers. I had forgotten that. I found it and was able to make the action I wanted.

I went looking for your website today since you did something like this in v10 I think, but I could not find it at the time. I think your appearing egg effect is great!
