Hi

Why my render is so flat and insipid ?
I use Octane 1.10, PMC, HDRI, GTX960
no post prod

Thankx

no reflections I think, and maybe gamma too washed out, so losing the 'ambient occlusion-y' bit?

is there a wall behind the camera?

too much light from different directions I think. There are no shadows being cast which means there is multiple light sources from different directions that are too strong and washing out shadows. I would start by turning off all lights except the main one (I would say a "sun" from the right coming in the windows). Then slowly turn on and tweak the other light sources.

yes, i have lost my reflexions, i dont know why ? perhaps so much lights source (blackbody) ?
i have lost my ambient occlusion to, that's why i often prefer DL.
and yes, there is nothing behind the camera
i'll tried with the sun on the right

thankx

Probably check if you accidentally pressed the colored clay mode button. That is why you lost all your reflection.

That is your problem, you should have whatever the project has, a wall, windows, etc... you can use the near clip option to see through the wall, currently your scene has just uniform light from the HDR, that is why it doesn't have any shadows, or contrast...

if you want to use an HDRI, set up a fake sun as an emitter plane. Larger emitter gets softer shadows and smaller will give you crisp shadows. Best results will be from a low power HDRI, using the actual light sources more.

it is a bit flat, needs warmth - yes the above advice is legit - you have everything rasterised - exact copies and alingment of clones that is flat in itself
- also play with all the tonemapping setting - the gold 200 adds a bit of warmth..
- also try using lights on one side with slight warm (red) and on the other side slight cold (blue) lighting, when they meet in the middle it gets interesting/adds depth
a bit extreme here > blue vs red Image

- also some slight noisy bumps and textures - materials look like flat RGB, slight bump because nothing is perfectly straight/flat in reality
- composition http://www.netplaces.com/photography/ta ... terest.htm
- rule of 3rd ..
