I used the same paper, but I didn’t use the script “Paper Overlay” to apply the paper to a layer. To do it this way, first select the paper you want to use, then fill the layer with a color. Next, go to the Menu Bar and select Effects > Apply Surface Texture and a window will open. The first drop down menu should be set to Paper. Then adjust the rest of the sliders to make the paper look like you want. Tip, I usually take shine to zero. I usually adjust the amount to 40% or less. I usually increase the softness to between .25 and 1. But this can change depending on the paper. Hope this helps.

How you did this canvas underground? It doesn’t look like the one on the video tutorial “001 New Papers and Skript Library “. Thank you

Thank you. I’ll follow your advice. I’m a new Corel Painter user and I already love it 😉 Have a good day
