A question :

Is there's a param to dark the shadows of the physical sun and sky lighting.
I know it is possible to have shadow Buffer (renderchannel) and tweak in comp but this buffer is quite heavy in rendertime and my render is enough longuer to use this trics.

I thought lower "planet reflectance" param will increase shadow contrast but it not seems to be enough.

Any other idea ?

You can make a brighter sun emitter, perhaps via multilight. that will give more contrast.

I would use the sun indicator and place an emitter at that location, make it far away for more parallel shadows, and small enough to give sharpish shadows, then turn physical sun off, and render with multilight.

With multilight you have control over sun and sky independently. Maybe you can play with that.

Thanks both for your suggestion, I will try all your methods.
Lowering the "planete reflectance" and the "aerosol reflectance" seems to work perfectly on my scene (thx Half Life for the trics).
