How to increase photorealism?

[fortminors]

Describe the issue

I am looking for a way to configure the camera/renderer so that the rendered images look more realistic.
At the moment, one could tell quite easily that the images do not look real enough.
Perhaps, there is a way to toggle a more time/power consuming renderer that would achieve better results?

I am adding what I toggle currently for the renderer below.

Minimal code example

bproc.renderer.set_noise_threshold(0)
bproc.renderer.set_denoiser('INTEL')

Files required to run the code

No response

Expected behavior

I expect to find a way that increases the quality of rendering to its limits

BlenderProc version

v2.6.1

Could you provide an example image which shows the lack in realism that you mean? The code you wrote only decreases the noise in the rendered images, but that is probably not what you mean?

[fortminors]

What I mean is generally, in order to increase the render quality, are there any options to choose from? ie for the examples this library provides, could I somehow tweak the settings to make them more realistic? Or is it mostly dependent on light and materials used?

Hey @fortminors,
sorry for the late response. In general, you get realistic images by having realistic lighting and good materials and meshes. You can take a look at the front_3d_with_improved_mat example, which uses high quality materials.
Also for realistic lighting, you could use a hdri environment map, as done here:

BlenderProc/examples/datasets/haven/main.py

Line 17 in 455cc0a

bproc.world.set_world_background_hdr_img(haven_hdri_path)

Thank you! Will have a look
