Masking / Clipping confusion

[jstnhllmn]

Hello, everyone. I dove in and bought all the programs.

Now, I have a 'best practices' inquiry:

 

How do I set-up the artboard so that the white dirt on the 'K' (a texture file) is actually erased (a layer mask? a clipping ask?), allowing the pink circle to be visible?

 

Sorry - I am completely befuddled by this.

Hi jstnhllmn,

Welcome to Affinity Forums

To do what you want you just need the texture (white background with the texture dirt in black) clipped to the text. Then select the texture layer (pixel layer) and go to menu Layer ▸ Rasterise to Mask. That's it. Check the sample file attached below - select the texture layer and go to menu Layer ▸ Rasterise to Mask. You will then be able to see the  green background through the letters,

I want to cry, that was so easy.

My thanks. Namaste!
