Light 'Spots' in renders

Anonymous — Thu, 11 May 2023 09:53:16 GMT

I cannot get rid of these spots of lights appearing in my renders... I have tried adjusting the global illumination settings and upped the quality but still no joy. Can anyone please help me? Attached example of what is happening.
My setting for GI are set as follows and it is still happening:
Diffuse depth = 5
Sampling - Stochastic Samples = High
Record Density = High

Kate,

these artifacts can be removed by amending the settings in the global illumination tab of the detailed settings.
Change Primary Method to "QMC" and Secondary Method to "Light Mapping" with Maximum Depth set to 32.
I have attached a rendering scene file containing settings I have used successfully that produces noise free images in a reasonable time (about 10-15min for 1920x1080 image of model with 27 light sources and 1.2M polygons)

Regards,
Scott

I am not able to open this zip file.
It is coming as .renderingscene format.
How to open it?

Go into your Photo Rendering Settings dialogue.
For the 'Scene' choose to "Select and Manage Scenes".
In this dialogue you can now 'Import' the render scene file.

But it is showing the settings of internal engine.
What settings you are mentioned there, it is not the same. I have attached the screenshot.(Screenshot 54)

I want to use this for other project, for interior living design.
I am not able to get the output properly.
I have attached that image also(Ravikumar-living Picture # 1.jpg) This is what I got.

But I want the output like this image (WhatsApp Image 2021-05-13 at 7.41.25 AM.jpeg) with proper light settings.

How to get this? Please help me

It seems you are using version 19.
That render file may have been for a newer version - the render settings have changed a bit over time.

Where it says 'Engine - Internal', you need to change that to 'CineRender by Maxon'.
Then go up to 'Scene' and you can choose from a preset scene or you can import that file - but I'm not sure if it will work if it was created in a newer version.

I want this type of lighting output, where I was wrong with the setting. I checked the forum and tried the settings, but not the proper output

How to get this? Please help me

Roopa A,
You have just quoted the same post you made before.
Do you have a new question or are you saying you are still asking the same thing?

Are you rendering with the CineRender engine?
Have you successfully imported the new scheme?
It looks to me that you lighting is over exposed.
I am not a render expert, but maybe turn the lighting intensity down.
Try using different preset render schemes to see if they are any better.
You should have a variety of default ones to choose from.

Barry.
