Something strange in this scene

Hi!

I'm rendering a simple wallpaper 1280x800 with a plane and two spheres.

With a different HDRI in the past i've a good image after 6-7 hours.

now after 20 hour rendering this is the result.

It's normal?

Thx

If those are glass spheres, then the IOR should be 1.52
Other than that I don't see any problem.

I see your problem...

Photoguy, there'sn't any mistake but the huge time consummation...

The other one was with same blendigo, Indigo?

Are you using a different HDR now or is it sun?

different HDRI...

ok.... Well it could be that the HDR just isn't as good...

Yes it was an HDRI problem! This is the same scene with a different HDRI rendered in 4 hours... it's better than the previous rendered in about 20 hours!!

In the second image now I've a strange effect (marked in red) and I cannot say if it's an artifact or is a normal glass reflection... what do you think?

As far as I can see, its the horizont line flipped exactly like it should be.
if you would try other (none reflecting) ground mat, you'll see it much better (checker for example).
