Draw material to render target not working due to alpha value

So I’m trying to get to send my material onto a render target and export it as a png. This is my render target set up that has been working well so far, in that I could use my other brush material on it and export it properly:

Here is the material setup that I am trying to copy onto the render target. It’s a proper material as I’m trying to copy the masks themselves that are being used to lerp between different textures onto the render target.

This is my blueprint setup:

The weird thing is that it seems to work, except that the alpha channel appears to be 0. When I disable the alpha channel in the render target viewer, it gives me the expected outcome but when I try to export it, it gives me a blank picture.

It needs to be in PNG format as well

OP did you figure this out? We are running into this issue now! It’s definitely something to do with the alpha channel.

did you figure out? what was problem? I have same issue!
