Hey everyone,

I’m seeing strange artifacts when using the particle system and having vignette enabled.

Here’s a video showing the bug, where basically, everything seems fine when the particle system starts, but after stopping it, you’ll see how the sprites turn into this giant colorful popcorn of sorts.

This is happening in Windows10 + Chrome.

Here’s a playground showing the issue (let it run for 10 seconds or so)

**SOLVED:**  
Disregard, problem solved by enabling tone mapping 🙂

(Just marking this as solved, as the forum doesn’t allow setting the original question as “solution”)

Solved in the original post!

Yup without tonemapping, the colors ends up fully out of range creating the weird artifacts 🙂
