How to make a Gradient Skybox with Stars in Unity | Shader Graph Unity

I have been learning about shader graph and its kind of amazing and we can do whole lot of stuff using shader graph and I started with a simple gradient shader for my skybox with stars in it and it looks amazing. We can also change it to match the look that we want for our game and also suggest some other cool shaders that I should try out.

Note : If you notice some sort of stretched out stars at either sides of your screen, use the tiling values to reduce it to a minimal amount.

If you like sparkling stars just add a simple noise node, make it scroll and multiply it with the power node of the stars.

If someone still has that unwrapping artifact, do this:

First route the G channel of the normalized UV into a Arcsine node. Take the output of this Arcsine into the 'A' of a Divide node, the 'B' of this Divide node will be a PI constant driven into another Divide node.

Now for the R & B values of our normalized UV: Drive R into the 'A' of an Arctangent2 node and B into the 'B'. Take the output of this Arctangent2 and Divide by TAU constant.

Lastly combine the outputs of the two remaining nodes. That is the proper UV. For the gradient split the RG(2) component and use the G channel. For Voronoi, use the RG(2) out.

Hope this helps.

Just to anyone stumbling onto this - doesn't work on latest version of unity for many reasons

For anyone that faces issues with newer Unity versions, just change depth write to forced disabled

That's so practical! Thanks for the tutorial 🙌

[menotarobo]

You helped me sooo much, thank you :)

[welcomelittlefellow]

thanks for the clear explanation. Great work!

I like the way you are solving the star texture issue with the voronoi node, but I have stumbled upon an issue. it seams in unity 2020.2.7f1 (idk about other versions), the skydome is unwrapped in a way that creates a nasty aberration in the form of a stretched-out line rotating around the z-axis. Does anybody have a fix for this, or am I just going to have to make my own custom unwrapped skydome?

How would you make a day and night cycle using this method?\

[SanLiuk]

what's the solution for hdrp?
Ther's no matererial sky box option for it

[paulmiddleton]

I had an issue with an error "The Current render Pipeline is not compatible with this master node". Which made the preview bright pink. The following resolved it for me. Hope it helps -
Right Click in the asset folder and Create -> Rendering -> Universal Render Pipeline -> pipeline asset (forward asset) -> name it anything.

Goto Edit -> Project Settings -> Graphics then Drag and drop the Pipeline asset you created onto the Scriptable Render Pipeline Settings (1st item).

Worked for me, hope it helps another.

YOU CAN MAKE A SKYBOX WITH SHADERGRAPH!!!! IM COMING RIGHT OVER

Hi The Game Guy, the result is awesome and thanks for the tutorial ! I got some troubles in my project, when i move my TPS camera, the stars on the skybox just shaking around until i stop moving. Did you encounter this issue before ? If someone got an idea, that could be helpful !

Hello, I have a problem. I'm trying to put the skybox in unity 2d, but when doing, so it turns black, I have the camera set to skybox and I put the material in lighting, environment.

I have issues with this in unity 2021
and this shader is not work😶

"see this warning, dont worry about it" but i do sir ... i do ...

In Unity version 2021 it does not have Vector 1.
