Glow motion arround object with Shader Graph

[tyronleo]

Hi to all,

I’m new to shaders and with the new Shader Graph from Unity I’m trying to experiment and archive some effects that I have in mind for my games.

I want to get something like this:

I want a glow effect to go arround my object. In my case it’s a square neon light, so it’s simple I think.

What I have so far, experimenting and unifying different tutorials, effects, etc.:

This is the current Shader Graph, i know its a mess and maybe there are useless nodes, etc.:

This is the tutorial I think it’s the most accurate to what I need:

Unity SHADERGRAPH Episode 13: Object and World Space

Thanks in advance for any tip that help me find the correct path to archive the effect.

Hi @tyronleo ,
You really can’t get a bloom-like effect other than maybe pushing vertices out like in a typical outline shader, like in this thread:

LWRP Outline Shader (Help Needed)

[image] Hey guys, i posted this on unity3d reddit but got no response yet so i’ll try it over here. Here is the post: I’m creating a lwrp shader to make outlines for my meshes since lwrp don’t support additional passes. The shader is set to transparent + multiply + double-sided so i can set the faces white when front faced and a property color when back faced. I could not find a way to just cull the front face in shader graph I think there might be a way to make this m…

But it will not look like that image in your first link. You might get some cartoony, somewhat flat effect most likely… If you want proper halos etc., it’s better to use post-processing effects and bloom, which is intended just for that.

Hi @Olmi ,

Thanks for the answer. I already have post-processing and the glow effect is not the problem really. I was thinking las hours on how about to have 2 materials. One for the glow effect. The other for the shader than simply do the effect of alpha all the object that I dont whant to see to get the effect that I want.
I don’t really know if that is possible, just it came to my mind. The problem for me is to get the effect of moving a texture, an alpha or color arround the object like the effect I want with a shader. Or if there is another way to archive that effect…
