Hi guys. While ago i made this exterior scene using free HDRi maps from Viz-People. Now, some time later i tried to render it again and this is what i get now, no visible shadows, no lights, i mean you can see the difference. I'm using Beta - 1 version now. The previous one was some daily build version. The good one is with a little bit of post work.
-
Are you sure the first one was lit with HDRI only and no additional light was used? Your second example looks like typical case when scene is lit with HDRI which has clipped dynamic range, something i would expect from viz-people and 95% other HDRIs available in the wild.
-
I'm 100% sure there was no additional lights. I have other scenes with the same maps and they are fine, but they are made with the new, Beta 1 version. Seems like new version is not rendering properly scenes made with previous versions. I'll try to install some older daily builds and will let you know if it helps.

Hi Romullus
I take it the clipping is not desirable
Is there any HDRI's that you would advise ?
Regards
-
Yep, that was something with the map itsefl. I downloaded them again and it's all good.

Check out https://hdrihaven.com/ - one of the best, if not the best source for high quality HDRIs. And completely free.

Agreed, I won't use anything else ;)

Oh wow !
Normally have such a difficult time with sharp shadows and good mids
All I did was slot it in and reduce exposure..
Boom , I think its very good lit, might miss something..
Thanks for the tip Romullus ( this is Max though )

I have also problems with too soft shadows. Do you know guys what is wrong?

Use a light material instead of a standard Cor shader. Hdri goes in the emitter channel.

A few days ago I also wrote about this problem, with HDRI de Viz, but !!
They deleted the theme because I passed a free hdri from the same page,
But I think that you can not do that around here.
I hope you can fix the problem and see here what is the solution

We deleted it? I'm lost..

Well, as a note, just because something is free, doesn't mean there are rights to redistribute it - something you have to check very carefully! So be sure you have the rights to share things before posting them here on this forum too. You can use the private uploader to share a scene for debugging purposes; or you can remove any protected (even if free) assets from the scene and provide a link for users here to go download the asset for themselves and add it back into the scene.

Yes..
I received an email where they told me that I could not ride the hdri de viz.
I explained that it was of a smaller size and that it was the free sample.
but they told me that I could not place.
So I asked that they delete it.
And I had to solve with Vray.
Although in the same way it did not remain as it is seen in the sample of the product

Hi,
it was me who contacted ozwald and asked about legality of that particular HDRI. I got an answer that HDRI was resized, but there was no mentioning about free sample, so i had to take the link down (topic itself was deleted by ozwald's request). If i would be told that HDRI was from free sample, it would be enough to mention from where HDRI was obtained and maybe provide some simple licence text.
Anyway, as i said to ozwald already, if you have material that you can't share publicly, you can always pack your scene and ypload to Corona's private uploader - only Team members will have access to it and they will use it for problem identification purpose only.

Guys, please, without offtopic...

There's nothing wrong with clearing some issues. And speaking of, I already replied to what your soft shadow problem is. ;)
-
Yes, I sure did not explain well that it was a
free sample, if not, I think I would not have mounted it so that
anyone would get it.
My language is Spanish, and I have to use the translator to
write in the forum.
Surely it does not translate well and in some cases it is not well explained
ha ha ha ha ha ha
anyway!! It's good that the subject is taken again.
very attentive to see the solution.
Thanks for the data to download free hdri
regards

When I applied the HDRI to Corona light material, the shadows did not change. When increasing the emission, it is automatically inreasing everything which of course is not the thing I want to have.
-
I think it's best that you pass the file to the Corona team
for them to do tests and thus give us a solution

I couldn't agree more! ;) @zbieraj, if you can send us the file that would be great, the private uploader link is in my signature below. Thanks,

Sent via Dropbox (file is larger than the limit on website).

Thanks!

I have also problems with too soft shadows. Do you know guys what is wrong?
Okay I have looked at your scene and to be honest I do not see anything wrong with the shadows. They are soft because the sun in the HDRI is covered by high-level cirrus clouds. Even in the test image from hdrihaven the shadows are somewhat soft/diffused also. If you're after sharper shadows, I'd suggest choosing a different hdri.

O...M...G... Ok, sorry, I'm stupid, I didn't realise how cloudy it was near the sun :D. OMG, sorry for disturbing your precious time :D

I'm interested in your case, because the same thing happened to me.
you could pass your file to the Corona team to see
why the same hdri but in Beta 2 drastically changes the lighting.
Thank you

By any chance, did the scenes use LightMix? And if so, are you viewing the same pass in the VFB (the Beauty, or the LightMix, depending)? I discovered recently that on render, the VFB was automatically selecting the LightMix and not the Beauty on initial render (presumably because the scene was saved with the LightMix open) - on a related note, then opening a scene that didn't have LightMix had the VFB default to the Direct pass rather than the Beauty.
Thought I'd ask you to check what pass you are viewing / saving from the VFB, just in case it's what you are running into (as, assuming you had the scene set up with the HDRI in a CoronaLight material and not in any other sort of material, there should be no change)

I think OP's case was solved long time ago:
Yep, that was something with the map itsefl. I downloaded them again and it's all good.
