Hi guys, testing new version of yafaray; ibl ligthing, some portals and IES lamp. Scene is in progress...material especially wood need some work.
Suggestions about rendering setting?

I would work a bit more on the materials, since lighting seems good. Particularly the wood material, I would make it less reflective. Could you post the radiance map? Also I would use at least two samples in every adaptive sampling pass.

This is image reference, my goal isn't to reproduce exctally, but a good render of course! More update and photon map soon.

Looking very nice!
I think that the lighting is better than the reference :)
But materials of the wood are very reflective really ... may be try to make them with more blurred reflections

Another render, I have modeling all by my self. Render time is very long...about 12 h! Hdri lightinhg (ibl samples are set to 128, no diffuse photons)produces a lot of noise and also glossy materials.

I try the sun&sky with default samples, rendertime is about 1h.

Hello,
Kool image you have there. I do prefer the lighting in the image using the HDRI light source, but 12 hours thats pretty long.

What sunsky have you used? If you used sunsky 1 try the 2 and select diffusse photon and caustic 16 sample worked for me in my interior scene.

How many diffusse photon did you used and did you add a real sun?

You seem to have an issue in your last image with the small window on the left of the door. Was that there after the render or when you added the background?

Thank's flagus for your reply!
Long render time is for high samples in ibl samples, hdri lighting produces a lot of noise, but scene is in wip, I try different setup to improve quality/rendertime.
Second render is whit sunsky2, 16 samples, no sun added.
Your right, is my postpro error on the small window, I fix it.

Sorry for my bad english!

Whenever you are multiplying your samples in subsequent adaptive passes, you need to start with very low sampling settings in the initial pass for IBL backgrounds and final gather samples for instance, since the progression have got a very fast acceleration after 5 or 6 passes. For instance, if you use common place 16 samples for a IBL background and you multiply them x2 in every adaptive pass, in 6 adaptive passes you are already using 512 samples for the IBL background, which is a hell lot. In my opinion is better that you use just 2 samples for the initial pass everywhere (IBL background, Final gather, Arealight samples, Path tracing samples, sun soft light, meshlight, etc) and multiply x2 in every new pass. With 6-8 adaptive passes you will already get a very good scene sampling. Also a 0.008 thresold should do for almost any scene unless you are sampling very dark areas.
