Applying filter to multiple layers

[Boscoverde]

Hello,
I'm wondering if this is possible. I want to apply a blur filter to multiple layers.

I have put the layers into a folder but I can change anything unless I do it layer per layer.
Do I need to go to After Effects for this?

Thanks.

Nest the layers in a symbol instead of grouping them in a folder.

Select the layers, right-click and choose convert layers to symbol, then apply the blur filter.

Thank you.
I have to get use to using symbols !

Okay, we get it, you have MAX RAM AND MEMORY. You don't have to keep telling us.

The idea of putting it in the signature is to not have someone wondering what system you have.

That's it.

If you post on different forums this info might be usefull. Nothing else intended.

Unless you're having a specific technical issue where your operating system and other specs are relevant, trust me, nobody cares.
