pixel shading vector curves works great until it doesn't???

[Otto Manuel]

Hi,

 I am still getting used to Affinity Designer's fantastic feature that automatically masks pixel painting or shading within the boundaries of a vector shape.

I have encountered several occasions where it was working great on some curves and then for some reason it will not work on another curve and the pixel layer is placed as an independent layer in the pixel stack rather than being automatically grouped as a mask.

Am I doing something to cause the problem? Is the function buggy? Is there any way to prevent the misunderstanding?

 

Windows 7 x64 and Affinity Designer

 

Thank you!

I figured it out; The auto masking function that allows for painting textures and shadows over vector curves does not work when the curves are not "closed".

The answer was simple, but it is a little detail that I never saw emphasized in the tutorials I had viewed.

Most of the time my curves were closed, so most of the time everything worked great.

Now I know why it doesn't always work and how to prevent or fix the issue.
