changing materials during animation
I was wondering if there’s a way to change materials on an object during an animation?
Even better, is there a way to cross dissolve between two materials
(each .png files in the color channel), during an animation.
Even better still, and what I REALLY want, is to do in a mograph cloner, driven by linear falloff????
Any of you expresso wizards have an idea?
Thanks,

For Mograph:
* create a material with the mograph multi-shader in the color channel;
* place the start bitmap in the first slot and the second bitmap in the second slot;
* assign the cloner a plain effector with all parameters except “affect color” turned off;
* set the effector to linear falloff and animate position.
Unfortunately that won’t, by itself, do any cross fading. The clones will be either one bitmap or the other.
As a workaround, you could do the following:
* In a compositing application, record an animation of the two bitmaps crossfading one into the other;
* Load the movie file into the first multi-shader slot and delete the second if you’ve already filled it;
* Hilight the first slot (Shader 1) and click the “to layers” button.
That will create a separate layer for each frame of your animation. Now when you move the effector it should do a cross fade.

Hey Adam, Thanks for the info.
I attempted to follow the first part of the instructions To get a multi shader to swap materials using a plain effector. Thats exactly what I need. I wasnt able to get it to work. There’s quite a few options in the shader as well as the effector. I was wondering if you could have a look at the project file that I attached and see where I went wrong.
Thanks again,
BruceHappy to look at it but I’m getting a 404 on the link.
