I'm going through "An Introduction To Corel Painter" from Ryan Church's website. The section I am viewing is about papers and in it he shows us how to make a new texture by capturing a paper.

He uses the selection tool and selects a part of his City Chase painting. You can find that painting in his personal artwork section. Then he goes into papers and uses capture paper and continues to create a background texture using sharp chalk. When he sketches with that brush you can see the texture from his paper forming.

I've done all these steps. I captured the paper and it shows up fine in the papers section.

But when I use sharp chalk, all I get is a muddy streak and not the texture I made.

How do I fix this problem? Thanks.
