Hi Ivantr very very Nice baked texture and depot model, but you really can make some independent illumination inside.....with night mode or permanent lights....
When you prepare all scene to bake the main texture with the sky light put some
Mrs area omni lights inside adjust they place in the walls and make some renders with the sky deactivated, in the
omnis select
shadows on and ray trace shadows mode, also in
the intensity/color attenuation make your preferred color type and and activate
near attenuation/show and
far attenuation/ show, adjust all radius of this intensities and make some renders
. when all lights are ok inside your depot activate the sky light and Bake all complete main texture
. Also in the tag effects you can add some corona a.lights and use then as directional ones bellow the depot roof or if you wanted only at night (night mode mesh) make a simple hidden box with texture and applay all a.lights with coronas in all building and you can have a effect like i show to you in the image bellow
.
P.s.Also if you want avoid in the main baked texture the granular shadows effects , you must increase the value of the
Sky light parameters in
Render/rays per sample generally the
default is 20 but this is not good enough
(more rays per sample more slow the render but better the render results) i found a very good value of
30.
