Falling dominoes to change material ID after they fall

[coilbookmedia]

Hi

We have hundreds of dominoes falling.  We need each domino to change material ID from 1 to 2 after it falls so we can assign a glowing texture to each fallen domino.   is there a script for it? 

Thanks

Is this what you are after? It doesn`t switch between Material ID`s however, but blends between the Materials using Vertex Color Map.

This was done with DataChannel->Vector->Curve->Scale->Vertex output. Instanced across the dominos.

Uses a Blend Material with vertex color map as mask.
