Hi, I am new to after effects and I am trying to follow some tutorials and I have come across an issue.
I create a null object and can animate its path with an expression. Then I am trying to link a particle to follow that path of the null object by linking/parenting the position of the particle to the position of the null object. The problem I have is that the swirl icon for parenting is not showing up under the position section under the emitter (I cannot get the parent icon or the expression icon to show up). And I am unable to add an expression to the particle's position either.
I am adding a screenshot of the open menu with the position of the particle selected and you can see none of the icons show up.
Is there a way to fix this, or am I missing a step?
