Great work my friend..

regarding your first question.. i think Dwight have a very nice idea and an invention of using an extra sun with -90 degree , usually this one is good... any way wait for a few minutes and our saviour Dwight will be here answering you

Thanks "Whatever" for your guider.
I find out 2 way to light the bottom face of an object
1) Use an extra sun - without cash shadow
2) Use Realistic method of the " Sky object"
- Sample 200 ( duo2.8, 1gb ram) , may be more on stronger system.

The second way make picture look more realistic than the first - especialy in the conner of wall&ceiling.

Hope to sharing the skill with every body.

Here are some test - same V-ray presentation

And here - Using an extra Sun object without cash shadow - there's no soft shadow in the conner of wall & ceiling..... Any way - it run so fast

When lights don't cast shadows, the rendering is extremely fast because fewer calculations are needed. The ideal is to have only one light that casts shadows....

Nice renders! as for your first question about lighting the underside of the objects, have you played around with the pipeline/ Graphisoft Emission shader? It works a bit like Max's self illumination settings, it just lights the material without actually producing any light.

Excellent suggestion, but that approach tends to make materials uniform in light reaction.

They lack modeling.

You'll also need a different material for shade versus well-lit and this can mess up the quantity calculation chart.

I find the "Undersun/Hellezon" approach copes with any dark shade condition without adding rendering time.

Sukhoi, looking at your exterior view I suggest more archictecural detail for the facades would add to the realism. Also the roofs look too thin. Interiors are great though.
