Copy / paste a layer on a mask

[steday]

Hello

 

Here my problem :

I want to use a black and white layer in a document as a mask in another layer on the same document.

I can't copy and paste the layer to the mask, because it is paste as a new layer, even If  the mask is in editable mode.

 

In photoshop we can do this. We can even paste a color layer on a mask, it is converted to B&W.

 

I have not found a method to do that in AP (except with a composite layer with the command "Create spare channel "), but I want to do that whith the RGB mix channel of the black and white layer ).

 

Am I doing something wrong or is it not possible ?

 

Thanks for answering.

Hi Steday

 

You can convert a layer into a mask by going to Layer > Rasterise to Mask. You can them move this in the layers tab to mask the object of your choice

 

Thanks
