# How to get rid of fireflies in my metallic materials / cycles (principled bsdf) [duplicate]

i've been working on this Project for a while now and i am struggling with fireflies all over my metallic materials, I can easily get rid of them inside Photoshop but i would like to render an animation of the scene so i need cycles to render free fireflies frames.

I've tried: -Increasing my samples and no matter how high i go fireflies keep apearing, they even appear more one my frame has reached 4000 samples

-tweaking my material node

-deactivating my reflective caustics

-tweaking light (scene is iluminated by an hdri, a sun lamp and 2 point lamps)

I think it may have something to do with the roughness map or maybe lightpaths or max bounces since there are a lot of reflective materials inside the scene but im not an expert in either so i cant find a solution
