Mirror material issues and emissive mat

Hi there, starting to use D5 here. amazing software!
I have encountered issues when rendering video of a mirror.
This renders fine as still image but in video it has severe crispy noise problems.
I chequed for duplicate overlaping geometry, changed material, changed the original model in various possible ways, turned off the Nvidia DLSS, updated to the latest driver and the result is the same.


Any guess and help? thank you.

EDIT: Also forgot to ask about emissive materials. ¿can we animate the intensity? i cant find the way.
If i want to animate the lighting of the scene and have some lights with emissive mat. then how can i turn it on and off?

Hi pablo1,
Thank you for posting here. From the screenshot, it is a screenshot of video rendering, right? Please turn off auto-exposure, then adjust the lighting, also the Specular and Normal of the mirror materials.

Second, currently it is a known problem that the mirror material does not perform very well when rendering a video, and we are working on solving this problem. Also you can try rendering video sequence, then check the result.

Regarding animating emissive materials, it is not supported yet. For now, we can only add keyframes to light objects, but cannot do that for emissive materials.
Thank you for your patience!

Regards,
Oliver

Hi there.
Thank you for you reply.
That is a screenshot from a video, yes. You can see there the problem with mirror.
I did not use auto-exposure.
about the mirror material, y did changed various settings and found no change. This is what i have now.


Anyway, in some scenes the mirror has this noise and others no, so i guess is not a material issue, right?

I don’t understand what you mean with this " Also you can try rendering video sequence, then check the result."

I think this may be due to the known problems you mention.

Anyway, thankyou for you time.

Yes, it is not a material issue, but a problem that needs us to fix. Regarding the video sequence, you can turn on Advanced Video Rendering widget, then render them and generate a video with them.
