I have a simple scene with a cube going upwards. The cube has emission material that changes colour (blinks) based on the cube's z-location (this is done through animation nodes).
I would like to bake the blinking effect into the material, but I was unable to figure it out so far. I'm using the "Set Keyframes" nodes with custom property set to emission color data path but I get "Could not set keyframe" error in the Set keyframes node.
Is it possible to bake such animation with AN?

$\begingroup$ Does it have to be animation nodes to animate the shader or could it be also an animated shader? $\endgroup$– ChrisCommented Jun 30, 2021 at 17:45

$\begingroup$ @Chris it has to be done through animation nodes as this is just an example of a more complicated effect. $\endgroup$– MartinCommented Jun 30, 2021 at 18:48

$\begingroup$ @Gorgious thanks for the suggestion, but the value you proposed also leads to the "could not set keyframe" error $\endgroup$– MartinCommented Jun 30, 2021 at 18:48

$\begingroup$ and an animated color in AN won't help? Can you tell us why do you need this baked to keyframes? $\endgroup$– ChrisCommented Jun 30, 2021 at 19:17

UPDATE
ok, i tried and i think i have a solution for you.
The node setup is this:
Of course you have to update this to "your" material in the expression nodes, but then it works. I deleted the animation nodes tree and the baked animation changes z-Position and changes the material.
result baking:
result after baking with deleted AN-tree:
