HDRI: No shadows without a Corona sun present

This has really been bugging me for a while but I just can’t get any good shadows in my scene with just a HDRI. I have tried several HDRi maps and its as though shadows practically don’t exist. I load my maps with 32 def exposure and set the gamma to around 0.75, and still the shadows are weak as hell. I even tried custom editing my maps so the sun is just a pure white circle with a very dark blue sky. I think maybe my problem is the highlight exposure? Both metal Ray and Vray require a skylight in the scene does Corona also require that? I will post en example tomorrow of what my scene is looking like right now. One of the maps I am use is peter guthrie blue sky sun maps so I am not using weak maps by any means.

send me any map with this problem, I’ll take a look

I agree, no problems with shadows from HDRI, if use good HDRI textrure.

Not quite the result I was looking for. I will get back to you Keymaster for getting you some files to look at.

I am able to get nice shadows but then we have a problem with fireflies, workaround with corona sun is to hide it from reflection but what can we do for hdri ?

Can’t we have an option to clamp the hdri for reflection only ?

Do the objects with fireflies have reflection? If yes, then you either need to blur this reflection, or use reflection environment override (with something without the bright spot)

Yes they have reflection

The difference with reality is the pixel scale. I will try to render it at a much bigger res to verify that.
