EXR Screenshot tool for UE 5

I found taking EXR files through Unreal MRQ very hard, instead, I would like to write a tool for UE 5 to take EXR screenshots directly from the viewport, I am an artist, but learning Python for tool dev, Can somebody suggest me how to integrate EXR export option to the tool or how should i apporch to make this tool real.

Not trying to stop you from making this tool, but think it’s already an included feature of Unreal

You can also call this from Python, see AutomationLibrary
