I think this is a simple fix with a setting somewhere that I have missed but I cannot for the life of me figure out why the boolean modifiers are not working properly in my renders.
Here is the viewport (please excuse the lack of textures)
And here is the render You can see that the boolean for the window isn't working. (The render is low sample with denoising and the light artefact is a reflection off the shower screen.)
I have double checked that the modifiers are ticked for the render and viewports, and have checked modifier and boolean object settings but cannot figure it out.
Here is the .blend file if you would like it: https://www.dropbox.com/s/ik3yul655e23nqa/Chris%20House%201.blend?dl=0
Thanks in advance for your help.
