How to save a fixed checker box as a transparent background

Question

Hi there, this is going to sound strange but let me try to explain, is there a way to ad a fixed checkered box image as the background layer and then export the final image as a transparent image ?

The reason I want to do this is there is literly no other way to render the lens effects [bloom and glare] from Vray in a seperate pass or as a transparent image in 3ds max, the only work around I have is if I render the image with the lens effect as an PNG with alpha contribution and one without, and add the png without the alpha as a blending layer set to linuar dodge over the png with the alpha, it works perfect blending with all typed of background except a transparent one which makes kinda sense.

So i was thinking of maybe blending those layers over a checkered box then exporting it as a transparent layer.

I know in nuke one can achieve this but is there a way to do something like this in photoshop ?

Thank you for your time !

Alright so I reread my question and it sound weird lol, let me try to rephrase it, is there a way to export a blending layer with a slodid background as transparent ?

Here is a few screens to better explain my situation

So the image ebove is the glare and gloom form a light saber I rendered in vray and saved it as a png without an alpha

This is when I blended the layer as linear dodge [note how it acts kinda like a transparent layer above the other layers due to the fact that you can see the layer below]

You can even change the backghround layer and the "blended layer still works and acts like a transparent layer, but when i remove the background it displays the defualt background it was rendered on but still blends with the other layers below it

The reason it does this makes sense to me because there is no background layer to blend it on, but what im asking is, is there a way to capture the final effect from a blending layer and export it witout the black background ?
