hello team, I'm sorry to write again on this topic, but !! in truth the CORONA times are very high.

I do not think I'm the only person who's going through this.

I love Corona, I like how he interprets the lights, the strength of his lighting, how easy it is to use it ....... etc.
That's why I'm writing to you because I'm worried and I do not want to be changing engines in different jobs.
Surely many do not care about the details of their finish.
But my jobs do need that detail.
My client sells products to decorate interiors, floors, walls ..... etc.
And he wants his product to be perfectly detailed.

Here I pass another proof of render times.
Please, I need your help, to know of decision to take
please
please
help
Thank you

Compare what's comparable, Corona is faster than Vray. Just set it up the same way. Forget Irradiance cache, use brute force instead, no light cutoff, 25 max ray depth for everything and you will have a good base to compare with.

I compare only what I see through work with corona and it was faster till few versions back (more recent versions are slower). The workflow is identical, the projects are identical and now the render time is 1x longer than before.
Before was around 3-4h/per render view, now from 5-6h+/per render view, and we are not doing anything differently then before.

I know it might seem super time consuming but if you could prep a small comparison of an identical scene using one of the previous betas and the current one, I'm pretty sure that the devs would appreciate that. Not to mention it would make fixing the problem easier / faster.

Take one for the team :P

^^ Exactly ;) I'll start with my results from last week. Interior was rendered with RC1,2,3,4 and B2 Final with R19.

RC1 Render time: 31:22


RC2 Render time: 34:25


RC3 Render time: 31:17


RC4 Render time: 44:44


B2 Final Render time: 33:01

Hi,

I will prepare the scene as soon as I can.
However, even with upper tests, it's possible to see a slower render times with newer version, but not as slow as we get at work.
p.s. I have the latest daily version

[..] it's possible to see a slower render times with newer version, but not as slow as we get at work.

It is possible to see whatever you want to see, but if you'll do quick math, you'll get following numbers from Ben's tests.

Interior: mean - 34:58, B2 final - 33:01
Exterior: mean - 8:00, B2 final - 7:51

I think that's faster not slower ;]
I'm not Corona Team member. Everything i say, is my personal opinion only.

Some time ago I said that the time between one version and the other was slower.
Ok that's not the problem,
The problem is the big difference between Vray and Corona.
when V takes 6 minutes, C takes 23
Using the same parameters, even C helped by denoising
I mean interior renders, not exteriors.
I know what I'm talking about, I have time using
Vray and Corona, and I put the same parameters in the 2
so I do not think I'm doing something wrong

I can accept a difference of V 6 minutes and C 8 minutes
but not so much.
