I was asking my self what can be the best way to do realistic embers (having a hard glowing yellow point, followed by a less glowing red trail)?
I tried using only motion blur, it gives a nice result, but it's hard to control the embers length, and also the shading.
The other way is to use a trail node with an add node, this makes me able to have more control on the length, but I still find it difficult to shade it well.
Any of you could have a better ideas??
Thank you !
