[spoiler]I’ll guess the one on the right, SWOONFINAL, is your render.
Where to start?
Give-aways:
The wood grain on the legs of the chair and ottoman.
Hand print on the seat cushion of the chair.
Little puckers in the seams of the upholstery on the chair.
End seam in the piping on the ottoman cushion visible in the photo.
Deformation of the upholstery in the photo that isn’t present in the render.
Woodgrain on the floor in the render is not quite right and the planking in the corner under the curtain makes no sense.
The seams between the floor planks look like gaps in the photo. In the render they look like black caulking.
In the photo the wainscoating and baseboard have clearly been painted numerous times and is rough.
The baseboard trim in the corner has a gap.
Edges of the rug isn’t perfectly straight in the photo and the rug has thickness which isn’t present in the render.
The grain direction on the pedestal f the little side table is wrong in the render.
Repeated grain pattern on the top of the table in the render.[/spoiler]
For me the biggest giveaway is the floor. A wood decking with gaps between the boards is never used inside in the world I inhabit. And the curtain on the left image just looks too good to be modelled - possible, but improbable.
About the right image:
I was wondering about the light source in the lower right corner behind the curtains, down at floor level “on the other side” of the wall. Just one of a few things I noticed among the
things others have mentioned.
Interesting, as that is how the floorboards are in my house funnily enough - it is 130 years old. And perhaps localised to some extent - so that as an implausible detail didn’t cross my mind.
And it’s made worse as I didn’t apppy the slithers and fill the gaps when I sanded the boards a few years back.
My energy bills pay the price now.
I didn’t give that a huge amount of thought generally if I’m honest as I grabbed the first approximate match from chaos cosmos.
It’s interesting to read that took people into uncanny valley however.
OT: I saw a similar construction in the oldest Helsinki University laboratory building from 1865, but it was an underfloor that was covered with about 3 cm asphalt. The same building had wood floors of thick planks but they were butt-jointed and joined with pegs.
First one (I’m looking at my phone in portrait mode) is real - the hem on the textile is part of the give away. Another is the texture mapping on the legs of the render.
