How to merge layers with a layer style in Photoshop?

Question

Adobe Photoshop

I have Photoshop cc 2015. I want to merge the layers into a single image, but on many layers there is a Multiply layer style and when I press Ctrl + E the layer style automatically changes to Normal. How to merge the layers so that the picture remains the same as I made it?

Answer 1

The question is not entirely clear, if you reduce 2 layers with different overlays, there will always be Normal.
Try Ctrl+Alt+Shift+E - this command will create an image from all active layers, but the layers themselves will not be touched. Or Ctrl + Shift + E - will bring all visible layers to the background, and the invisible ones will not be touched.

Answer 2

If the Flatten image does not help (Layers menu or right click on any layer in the layers panel), then collect all the layers into a smart object, and then rasterize.
PS By the way, I made a test file, set the multiply mode and even Merge layers merged everything normally, without resetting the overlay style.
