could you explain me how to remove the colorful noises in the photo attached?
it happens when i add a spotlight to get bloom/glare effect.
i rendered maxsample up to 5000 but it didn't go away

Hi,
probably you have overexposed pixels, try to increase the Saturated to white parameter, in the Camera Imager node.

it cleans out big noises but small noises can't be removed

The noise depends from you lighting, materials, and kernel settings, so difficult to say from the render.
Also camera Imager settings can have an impact on noise.
Are you using Path Tracing or PMC kernel?
Please post some screenshots about light, diamond material, camera imager, and kernel settings.

Hi,
I have a missing plugin error: Anyway please try with the following version: I have cjanged the Light ID of one light, and enabled the Transparent Emission option for both lights: Then reduced the GI Clamp to 10, copy pasted the Exposure from the Camera Imager to the kernel panel in the Expected Exposure field, and enabled the multi light passes, so you can evaluate each light and environment separately.
I don't see colored noise, but only dispersion, anyway, I have enabled the AI Denoiser for the final touch.

Looking forward for your feedback,
ciao Beppe
