Hi Everyone,

Im having trouble sometimes getting my shadows darker. They keep reminding us that a good image is so much about the light and the shade but I cant get the shade to really punch it out.

Ive tried changing the sun size
Ive tried changing the sky and sunset colours
Ive tried moving the sun around through the Rhino control panel to NSEW and high and low
Ive tried changing the materials from glossy to smooth etc
Ive tried changing the ray epsilom
Ive tried changing the sky turbidty
and the specular and diffuse depths and now Im stuck.

I have only the rhino sun as a light
There is no background scene to reflect light.

On the attached image I wanted the sides away from the sun to be a lot darker and to actually see a shadow line across the body cast be a fin or the head.

I can see the shadows on the preview in rhino but not in Octane.

Love to hears some ideas.

Cheers

Double check your scene scale - since it looks like a ray epsilon issue. If not, then the Daylight lighting environment might have too much light coming from all directions to get the look you are after, and you could instead use geometry emitters, or something like the HDR Light Studio plugin to get the exact look you are after.
