Daylight system

[falcon76]

Sorry for the, maybe, stupid question. Is it possible with the actual daylight system to produce soft shadow?
Like in other engine turn off the sun and leave on only the sky. Or can I produce soft shadow only with HDRI?

Thanks

only with HDRI, the sun will render sharp shadows for now, but in next updates we will get a way to control that (Radiance dixit ) There was some thread were he explain that new feature in more depth.

Maybe with more turbidity and/or masking sun with clouds...

For what I have tried so far, increasing turbidity and power (to compensate the light loss due to turbidity) gives good results.

I'm not english but I think that is the the right terms to use:

It is for sure related to penumbra. If it exist, don't know how to use it. In fryrender I can turn off the sun (using the lightmixer), so only the sky is used for illuminate the scene and produce soft shadows.

Yeah, you are referring to penumbra, but you need the sun to cast the shadows anyways! It does work properly yes, although there is no parameter for "sun size" in order to control the amount of penumbra... if you want a more accentuated effect you will have to scale up the scene.

Ok, thanks. I will give some try.
Anyway scale up the scene is one of the things I prefer not to do. But extremis malis extrema remedia!
