Hello guys!!
I'm trying to make a new night scene and i can't get good shadows... can anyone help me with the ligthing??
I'm using a corona sun 19.30 hour, with hdri , portalmtl, two corona ies lights on the walls, and one corona light sphere above the chair to get shadows .
I'm waiting for your answer Thank's!!

I'd suggest to put grey mat in material override to clearly see how lighting and shadows act.
-
Here is the override mtl.... with the exact same lighting and settings ...
-
I can be wrong, but basically it means that most of your picture is delivered by unrealistically high reflectiveness of materials. There's pretty much nothing you can do with lighting, unless you fix your materials.
-
Thank's!! you mean the floor i suppose... i'll try it with another an see...
-
Here it is with another floor.. still i don't have the result i want...
i putted another one rendered with MR that kind of shadow i mean....
-
Sorry, i must admit it was silly presumption about reflectivity. It can't be true. But on the other hand, i find it hardly to believe, that there's no change in settings between your normal scene and the on with grey materials. Did you adjusted exposure compensation?
-
There is a pretty big difference in the lighting between the grey render and coloured....I assume you've enabled a plain white environment light for the coloured renders. It seems that your problem is that the ambient light / environment light is completely washing out the scene = no contrast in shadowed areas.
My suggestion would be to completely turn off all lights in the scene, render a jet black coloured render, then turn on only the spot lights (do not turn on any other lights). Then start to tweak the rest of the lighting until you find a good balance.

I also suggest you to make the white walls in gray tones + dim the "ambient" lighting and add some cool spots from the floor on back wall.

I think if you want to make your image pop, do what Romullus did, make your environmental lighting a tad darker and raise the brightness on the lights. You'll get the dramatic effect your looking for, specially highlighting the stone you have on your scene. Which also brings me to say you might want to fix the map to show proper displacement and bump. Overall its has potential.

Thank's all of you for your answers!!! I'll try what you said and i'll come back!!!
-
I increased dramatically the intense to 6000 and lower the exposure and highlight compression an i got these results..
it looks much nicer i think although i have very sharp shadows on the floor...
-
Looks Punchier, now you know what to do to increase dramatic effect.

Yeh!!! Thank's!!!
