It is built into the editor. This effect will work out of the box if it gets added into Team Fortress 2 without needing any additional scripts.

Do you use custom scripts for the lighting detection, or is this built into the particle editor?

Wow that's really clever

This is absolutely amazing.

ooohh this is COOOL

hope it get's in!

this is really cool, damn

this ♥♥♥♥♥ pretty cool

i could b yuor angle.... or yor deval

Honestly would prefer stand alone versions

what kills me is you can't get nice effects like these on non tiered hats, very cringe

put this in the game immediately

Man that's so cool

Wish the horns didn't look so much like clown hair

I actually LOVE the idea of a lighting reactive unusual, this is sick

this is so damn cool omg

Maps have so many different lighting conditions. We tried to make it optimal in most lighting conditions. This does mean that both effects will be seen at the same time in specific transitional areas. We minimised that by greatly reducing the color saturation on the effect. For this kind of effect, the only way to make it fade faster is to lower the lifetime of the particles. Unfortunately doing so will make the effect lose its shape.

In short: No. We were very limited in what we can do.

Could you make it so it fades faster? Cause at some points during the transition we have both effects at the same time. Maybe different shape for the horns as well? Cool idea otherwise, very... unusual.

cute idea, especially with the lighting stuff. But as for how it actually looks and the concept I don't like it, nothing to really do with the tech.

I never could've imagined something like this was even possible for unusuals! Not only is it a cool mechanic, the theme of the unusual fits it perfectly too!

Cool

Ooh not a bad idea, I'll think about it!

this is so cool. so very cool.
but i think just “Duality” as a name would be a lot snappier, imo!

really cool concept
