I am doing this job, it is an office-like environment of a real estate agency, as you see it is illuminated with natural light and artificial lights. I ask you if you can give me suggestions on the rendering settings, I use the Presto engine and I don't get the results that I expect from Thearender. Thanks for your answers

I'm far from an expert, but I would add the different lighting elements one by one
- first an HDRI sky for lighting in stead of the standard sky. The ones that come with Thea are already tonemapped. Very convenient.
- adjust the exposure
- turn on the sun if desired (aligned with the HDRI)
- turn on the interior lights (on a very sunny day you probably wouldn't use them)
- add some AO to fill in some dark spots, but less intense than now and with a larger distance. Bit too much now.

I'm also a big fan of the "filmic" tonemapping

Werthen's approach is pretty much what I would recommend.

If you absolutely need the interior lights on, then I would start with those (turn off any HDR or environment lighting) and treat them as the main light source. I'm suggesting this as you would expose for the interior lights (which need real world power values) when photographing a setup like this .

Once you have the exposure settings right for the interior lights, then I would add an HDR/sun. Light coming in from outside will be blown out, but that's normal. If it's too harsh, then you have a few options. You can export the render as a .exr and balance out the lighting in post. Alternatively you can save one render exposed for the interior and one for the exterior and combine the two of them in post. You can also cheat by reducing the power of your HDR/sun, but I find that this detracts form the realism.

I tried to follow the directions, but I'm not convinced by the result, any other suggestions?
Thank you

I find it odd that you can light up that ceiling so well. It reminds me of cases where AO is too high for some reason yielding an unnaturally high diffuse ambient lighting effect (which seems to be a side effect from ao’s intended use).

It seems unusual to me to obtain more satisfying results with a free software like Blender (Cycles)

I also meant to ask if your white wall materials are 'realistic', ie, with at least some roughness, a reasonable reflectivity, a color within the acceptable saturation limit, etc.

Great to see more Blender vs Thea comparisons!

the walls are white and with not close views I think you shouldn't see bump

Would you mind sending me the scene? I would love to have a look at it. Send an email at support@thearender.com.
Make sure that you save the scene with all the dependencies. Open Thea Browser, click on the "Box" icon and create an archive of the scene.

Thank you.
