Arnold Render View exposure is different to Max Render view (standard)

Hi.

I would like to know why the Arnold Render View shows a different exposure than the Render View (Max standard).

To see it, I have to lower the exposure to the minimum and after that it is shown with the exposure that was previously configured in Max's camera.


The Physical Camera is set to see it here, in render view standard shows good: if you see in Arnold Render View I have to slow down to minimun the exposure.


If I render with Arnold Render view to default the exposure is different, I mean is to bright in 0 (by default). to balance I have to slow down to minimum.


Is there any problem o I'm losing something?


Thanks.

I found a problem (I think).

When I use Arnold Render View to final render and check in denoiser tab (Output Denoising Aovs), start the render and finish. Then I find the Denoise Image Input and browse and select in the input.

When I press the Denoise Button the log shows this:

Loading file "D:/Arq. Miguel Soto/Downloads/Escena interior (1)/Escena interior/renderoutput/prueba1_Noice_Input.exr".

Using feature AOV 'denoise_albedo'

Filters for feature and light AOVs are different: denoising works better with matching filters.

Using feature AOV 'N'

Filters for feature and light AOVs are different: denoising works better with matching filters.

Using feature AOV 'Z'

Filters for feature and light AOVs are different: denoising works better with matching filters.

Working with 1 frame at 1x1

Warning: some output paths were ignored, since outputs always follow the input file layout.

Start denoising (patch radius 3, search radius 9, variance 0.5)

Finished denoising


To resolve this I had to disable Arnold Render View and Render it with Max Render View. With the standard method it generated a new Input Image and with this I could generated Denoised Image.

The Arnold Render View is for IPR, not for writing files to disk.

Let me see if I understand.

The Max render view does not show the exposure correctly and the Arnold Render view is it showing it?

Which of the two views is reading the configuration of the physical camera?

What would be the best recommendation to integrate Arnold Render View into normal max work?

3ds Max exposure control is not applied to what you see in the Arnold Render View. The Arnold Render View is straight from Arnold.

The 3ds Max render view isn't the direct output of Arnold. The Arnold output goes through 3ds Max first, where the exposure control is applied.
