Can sShapes function as a mask?

In the following example, I've created an sShape that is a white rectangle having 7 red stars on top of the white strip.

I want to mask part of it, and tried to use the sBoolean to 'intersection' formed by an sEllipse over the white-strip-stars.

But the output of the sBoolean is only the sEllipse over the white rectangle. Specifically, the sBoolean ignores the red stars.

(I know how to use conventional masks outside of the sShapes vector environment, but am wanting to use a mask inside the sShapes environment. This is so that I can magnify the size without the image becoming a bit-mapped mass of fuzz.

Is there any way to do masking inside the sShape environment prior to it being sRendered?

(In the example, in the sBoolean node, swapping the foreground and background inputs does not make a difference).

I wonder if there have been extra features added in Davinci 19?

If you select 'keep' instead of replace where it says 'style' the stars will be just fine.

Thanks. I assume you mean, in the sBoolean node, at the STYLE MODE menu option.

As shown in the screenshot below, when I click the menu, there is only the REPLACE option. There is no KEEP option in the pulldown menu.

I ascertained, from a YouTube tutorial below, that the KEEP option is only in Davinci 19.

Can you confirm that you are using the Davinci 19 beta?

Tutorial where it says the KEEP option is part of Davinci 19 at 2:26 in the video.

That's right. I'm using the 19 beta. For some reason I always do run the cutting edge of technology

I managed to test Beta 1 DVR 19 and, yes, it does work. But I had to use a sBoolean (and not an sMerge) to combine the red stars and white rectangle.

Whereas, in the version above - where the red stars and white rectangle are combined using an sMerge, it did not work.
