Hey everyone! I'm having a weird issue when rendering where, on specific frames, there is consistently solid white dots on the render (in mantra). It isn't like noise, and it only happens on specific frames. It happens on frames 472 and 362 regardless of the camera I use. I've attached images of what I'm experiencing. I tried looking around online and the only thing I found was to try lowering the color limit value, but the issue persisted and clamping that value too much made my renders ugly haha. Any help would be appreciated!

Are you using HDRI to light the scene? Try to tweak it by lowering down the brightest spot value a tiny bit at a time until the “fireflies/hot pixels” are gone.
Do check if the fireflies is NaN (Not a Number) or just really bright value. There are free tools out there for AE and Nuke that detects the problematic pixels and uses the surrounding pixels to fill it in.
