Simple post process material not working

Hi everyone.

I’m trying to setup simple post process material but it’s not working as I expect.
I just want to lerp to colors (blue and yellow), but got strange behaviour (scene color not changing while changing Lerp aplha parameter) and is always total yellow.

What can be wrong?

So the issue was same names for Vector3 parameters. I don’t know whether it’s a feature or bug.

Did you ever figure this out?
