Masking With Multiple Layers

Requirement is to create a comic with three frames.

Every frame will have a background image as shown in the attached image.

Right now background images of all frames are overlapping with each other.

I need to mask backgrounds of all the frames so that the part of background image inside the frame will be visible to the user and the part of background image which is outside of the frame will be masked. So the final output should look like the following image.

I can't remember the exact option, but what you're looking for is Blend modes.

Click on a sprite, and under effects, you should see blend modes.

I believe there is a example on the Start Page that demonstrates all blend modes.

Thanks Jase00 and alextro for your response.

I'm still not able to get the desired output. In my case multiple layers are involved as shown in the attached image.

In every frame there's a background image and then there are foreground item images. Also there's another top layer which is having frame structure with black color.

Now at any point in time, images from 1 frame should not come on top of images from other frames.

Kindly share your thoughts on this.

little example of a potential implementation, let me know if this works for you!
