Actually if you go to an explorer and find a ball for e.g. - then
navigate into the ball, you will see a blue mat node, open that, then
open the surface node, then the shader node where you will find a colour
node - inside this, are all 4 divots for RGBA - each can be animated
here, or have an expression added or whatever!!
Hope it helps

Actually, the balls change to white in 5 frames *_once_* they hit the

are a few hundred balls with their own timing.
I know I can create a new pass and new MAT anim but that would have to
be hand-adj in the dopesheet for each ball at the frame it hits the
ground.
I don’t mind the labour, I’m hoping to save some time and hopefully
learn something new (in case they decide to double the amount of balls
again to 500).
BTW, the “RGB color” does not allow for an expression to be created.

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.
