Re: Bouncing/Blinking

Hmmmmm... well assuming you have a flat ground plane you could link the color to the global y position so that as the balls neared/hit/rebounded the ground their color would change.  Basically as they reach a certain point in the global Y (above the ground) the color changes.  If you have multiple ground levels then this would be trickier.  Perhaps this is something that can be done in post?

Hello,

 

I have a scene that started with a few random 'bouncing balls' in military formation that has now turned into a few hundred random bouncing balls still in military formation.

 

Now the client would like the balls to 'blink' (basically change color to white over 5 frames) when they hit the ground.

 

I tried to apply an _expression_ to the material (RGB values) with no success. It seems that feature is N/A.

 

Is there a miraculous fix for this scenario or am I SOL with a one at a time modif?

 

Thanks and have a goodday.
