Hi,
I decided to switch from yafray to indigo for my architectural vizualisations, so I will post here my very first test renders.
I'm quite happy with this first try althought there are still some things that bother me, like :
_ The sky color : how can I get a clear sunny day ? I tried to change some settings (turbidity, sky gain, white balance, aperture radius) but the sky remains always too dark. Here are my settings :
<sundir>0.650663 0.328699 0.684540</sundir>
<turbidity>2.000000</turbidity>
<sky_gain>0.005000</sky_gain>
_ And for the moment I can't get the textures to show. But I gess I have to search this forum some more...
INDIGO RENDER :
And some previous yafray renders for comparison :
For information this is just a typical house that you can find in the middle-west of france (well, maybe too big to be the average house, but anyway).

Another test and... another problems !
I changed the place and direction of the sun, and now the scene seems to be lit by a spotlight... the center is much brighter than the borders.... why ? Is it too near the house ?
Oh by the way, I tried to use a hdri map, it works fine, but it tends to produce very soft shadows... so I prefer to use the sun in blender in order to get exactly the lighting I want.
I finally could apply some texture (the wooden terrace in front), but it is much darker than the rest of the scene.
And I've still got that sky problem : it's too dark, like at the sunset, while in my scene the sun is situated just on top of the house...
I played a little with the tonemapping settings, but it enlightens the whole scene, so if the sky is ok, then the house become totally white.
So I don't know exactly what to change in order to get a correct outdoor lighting... the place of the sun in blender ? or the tonemap settings in the xml file ?
Well, here are my settings :
<reinhard>
<pre_scale>0.9</pre_scale>
<post_scale>0.9</post_scale>
</reinhard>
<skylight>
<sundir>0.226315 -0.526516 0.819489</sundir>
<turbidity>2.000000</turbidity>
<sky_gain>0.005000</sky_gain>
</skylight>

hdri and soft shadows: the shadows depends of the hdri picture, you need a hdri with a strong sun, then the shadows wil come harder. The sun model in indigo is very simple... so don't expect to much
textures: note that texture color gets multiplied with diffuse color of the material, so if you have a blender material with a COL texture you should set the blender diffuse color to white.
