I’m following a Unity Shader Graph tutorial to make some fire effects, switching things around as necessary.
Around 7:10 is the final setup.
My nme as it stands here:
It’s looking pretty close, but I think what doesn’t translate is setting up the albedo and alpha explicitly, so it’s a bit off. How would I be more specific in making this a luminous fire thing?
I’d love to hear other ideas on how to improve this shader as well, since I’m learning everything all at once.
I did a quick test here :
As you have seen, the idea is to have at least 2 layers of noise going at different speed. blending them together and you get the intensity.
With this intensity, I sample a gradient for the color, and I use it as well for the alpha. Less intensity = more transparent.
You can change a few things with a texture instead of the voronoi ‘disk’ shape for more details.
Thank you for your input. I’m following that part, having two noise nodes at different speeds to make some movement.
I think my biggest question here is how do I make the texture glow brightly, like a fire.
a post process maybe ? Or you can add a 3rd layer with added intensity/color on top.
What nodes manipulate intensity?
You can use a ‘add’ node for example. Or a ‘scale’ node.
