We use a dot product on the normal map and an upwards vector to simulate light scattering and illuminating the clouds from below. Using HDR colors combined with a Bloom post-processing effect on the camera can make it look even better!

I know a shader exists to blend between two skyboxes, but it won't work with the new procedural skybox.
Also make sure to set the clouds normal map texture property to ‘Bump’ mode on the blackboard.Normal map strength was set to 0.8 for the example:Add a new Vector1 property for clouds brightness, and a new add, subtract and multiply node.Multiplying the texture by the Main Light color output will make the color of the clouds dependant on the color of the directional light in the scene. Publication Date: 2020-08-13.A special type of Material used to represent skies. Now that we have a sun sky and some basic clouds we can start reaching for the stars!…(yeah, yeah..)…Add three new Color properties for the night-sky colors and add two new Vector1 properties for the night-sky exponents:Swap the three color and two exponent property nodes with Lerp nodes and connect them in the way that you see in the diagram below.Now that we can transition to dark night colors we can start adding the stars layer to the skybox. For this, make a new Color property called Clouds Color and drag it onto the graph, also make a new Blend node. :Want to learn how we can access the properties of this Skybox ShaderGraph from a C# script to create a Day/Night Cycle for a game next??
I can't find a way to use a night skybox which will slowly appear (blend) to replace the procedural skybox when the night comes. Usually six-sided. Find this & more VFX Shaders on the Unity Asset Store. We could set the sun’s position in the sky by hand, but I would like to have it follow our main directional light! Same thing with sunrise/sunest - we use the reddened version of the light color from earlier and remap the colors. Make sure to set the Alpha Source to Input Texture Aplha in the import settings and also make sure the texture has an Alpha channel, you can see if it has one in the preview window if you see a white A after RGB :The node setup below generates an infinitely large flat layer for a clouds texture:We can blend the transparent clouds texture with the sky colors and the sun, using a blend node. I do not want to completely replace the skybox with a new image, I just want to add detail to what I already have. These are our UV coordinates!We can convert this into a subgraph, so we don’t have to look at this anymore!
We still need to mask our cloud effect, and it would be great if we could control how high the clouds appear along the horizon!We could stop here, as we are already at it for quite some time now, but I don’t like the harsh intersection between the sky and the ocean below it. Also create 4 new inputs on the Output node corresponding with the outputs from the Custom Function node:If you look at the Blackboard, you’ll see that underneath the name of the Subgraph in a darker tint grey you can specify where the subgraph is organised in the node creation menu. My currently untitled game (I want to break down the general structure of my shader, so you can build your own skyboxes on top of it! Keep in mind that this is not exactly the shader I am using since I like to tweak it a lot, but the features are the same and you will be able to easily extend it. As a capstone project for my program at Michigan State, I worked on a procedural Skybox shader in Unity. Below is a breakdown of my node setup and how it all works. Cubemapped skybox and reflections Creating Cubemaps from Textures. So let us try to blend that edge, and we will be done!And with this, we are done! We use noise that is multiplied very subtly over top of our skybox to give it a little bit of texture. Plug it into the UV input on the Now let us finally put some colors into this thing!
The horizon uses a similar technique, except instead using the absolute value to grab just the middle of the skybox (based on the ground location) and then using a user input to control the softness.There's a lot of fun with numbers here, so I won't get too much into the nitty-gritty. We just need to create a Vector3 property, set its reference to “_SunDirection” and untick the We will be using the dot product of our sun direction and the view direction of each fragment to see if the directions align. The user can control the stretching, tiling, and offset of the clouds to manipulate and move them during runtime. Post was not sent - check your email addresses! Open the lighting window by going to the menu item. You might need to tweak the sun size first, I recommend starting at a value of ~0.1, which is still pretty big for most cases. The example shows the opacity at 0.5:Adding support for a normal map texture to suggest depth based on the direction of the light. A Unity window that displays information about the currently selected GameObject, asset or project settings, alowing you to inspect and edit the values. Then we subtract the result from our first sun, saturate that value and we are done with our moon shape!
4. 2.
I also take the absolute value of that dot product and subtract it from 1 so that I can get a picture of when the sun is at the horizon.I use the normalized world position from earlier to mask out the verticality of the skybox, then remap it so I get a value of 1 at the horizon.
