Very low rez and blotchy

[alexworx]

I am trying to figure out why I am getting this quality out of my renders. I have enclosed the settings as well as a image file with and with out the denoiser.
I am using a vraydome light with a hdri map and a vray sunlight lighting the space.

Any ideas why I would be getting this quality?

Thanks
Alex

I'm having a deja vu... didn't you post this a while back? It seems the noise is coming from the windows, are there any lights there or it's just the environment?

Best regards,
Vlado

Your correct Vlado I did post something on this a few weeks ago. I never found a solution and I got busy on other projects. But now I am back on this. I think I found a solution. I added more lights coming from the cieling and that seemed to help. I am rendering some test now.

I will posts when I have something.

Thanks

Maybe its something like problem I found and write about in this thread: https://forums.chaosgroup.com/forum/...or-better-vray - System section - point 3.

This is tests I made.

First bad picture - camera exposure set to 2 EV, no color correction is made in VFB. Good second picture - camera exposure is set to 8 EV and picture is lighten up with VFB color correction exposure settings. No other changes in scene, only camera exposure. No antialiasing settings, no subdivisions, nothing. Only camera exposure can do this bad lighting/shadows. Dont know if this is normal.
