Is there a way to make a material that looks like a spark?
I want to create a sphere that has a brightness like a spark. To give you an idea of what I want, it’s something like the stars in the background of this picture:
And it must be a material used on a static mesh, not an image set as a background. I want to know how to create a material that emits light like these stars.
I think I can use Niagara effects, but I’ve read that it could be very expensive.
Niagara effects “can” be expensive but they are not by default . You just need a simple star shape (Doesn’t need to be realistic you can just draw it in the paint ) texture and connect it to emissive input of a material. then you can multiply it by a color and use time node to make it blink as well .
Also you can try using radial gradient node instead of this star image and connect that to emissive . see which one do your prefer ( if the light is not enough you can multiply it by a number using multiply node .)
I’ve been thinking about your solution and I don’t know why I need a star shape.
I’ve used that image because it’s the best example to show what I’m looking for: a bright dot like a spark. I don’t need a dot with the shape of a star.
