Effects and Smart Filters Ordering

I was short on time yesterday, and could not give more detail, but there's not much to it.

By using separate layers for the gradient effect, you can move, free transform, adjust the blur etc.  I started with a horizontal black bar which I made a Smart Object so I fine tune the blur amount.  Then copied that SO.

I mentioned the texture being non-destructive, but it is not really relevant.  Making that layer an SO as well, and then using Camera RAW > fx > Grain (which is one of my favourite noise generators because it is so flexible) you can again fine tune to get the right effect.

If you had needed to apply the texture to an underlying layer, then start with a 50% grey layer, add the grain and set to Overlay.

Note, I have masked out some of the grain effect so you can see the before and after. 

Puta copy of your product layer into the smart object, to help with positioning. If you used an adjustment layer as I did, the smart object canvas size should be same and layers register.

Then toggle the eyeball in the smart object for product layer. On to position, off when done

Paulo1988  wrote Hi, I'm trying to make a texture for some product photography. It is made up of a gradient with noise, blur and smart sharpen to match the product. My problem is that to make this work I have to put the gradient effect inside a smart object to have the smart filters effect it.

Smart object layers can have several's smart filters attached to then why do have to apply the  filters  to the object. Why can you not simply filter smart object layer and clip a gradient fill layer to the smart object layer and blend it in?  You can have a mask for the gradient overlay layer. A mask for the Smart Object layer and a filter mask. All can be Adjusted independently including the gradient fill layer.  The only problem I see is that the Filter mask can not be linked to the smart object layers content. So if you have a filter mask that is masking the smart object layer content. The filter mask will not reposition if you move the smart object layers content You would have to manually move the filter mask.

I'd use several layers for the gradient so you can move and adjust.

You can add the noise/texture non destructively on it's own layer using Overlay.

Combine all the layers into an SO if that's what you need.
