Thank you for the reply. Sadly the solution is not viable on my case. There are 1979 small lines in this layer. Is not efficient to apply the effect to each one of them. I wonder if there is a way to do that by creating a expression that targets the mask 1 to mask 1979.
Does anyone has another solution? Is it possible to create a loop that targets all the masks without copying the style to each one of then?
Thank you in advance.
