Highlighted quality issues

I found that the highlight of the babylon didn’t seem to be particularly good.
Below is the effect of my recording.

We need more information from you to understand your issue. The top video looks very good, the bottom video is blurry.

What did you do differently in creating the two videos?

A simple playground with just one mesh where you apply highlights together with what you want to change would help you get answers.

Highlighting lines is the main reason of all the artifacts. It is a one pass blur for perf reasons but a line can easily be missed in the sampling. this might work better relying on glow which does 2 passes but ultimately a larger line would be the best.

Thanks for the reply, I will study it.
