Sky Clouds HDRP: Fluffy Cloud Shader for Amplify

Links: Manual

Sky Clouds is a cloud system (shader + meshes + scripts) that gives you beautiful fluffy clouds that look great at close range but also from a distance.

NOTICE: The asset works on its own but you'll need to get the Amplify Shader Editor if you wish to edit the shader.

This is for HDRP only!

If you want the URP version please check out Sky Clouds URP.

HINT: If you already own the HDRP asset then you'll get a big discount on the URP version ;-)

😎 Easy to use

No coding skills required. Simply drag in the prefabs into your scene, configure the materials and you are done.

💫 Animation

Clouds surface shows animations and uses tessellation for close up details.

📚 Lots of examples & documentation

✔️ Full Source Code

I publish this asset with full source code because as a developer I know how annoying it is to not have source code access. If you like it then please remind others to purchase the plugin. Don't just copy and paste it everywhere. Thank you ❤️

✔️ Supports Unity 2022.3+, 2023, Unity 6 ... LTS

If you are on 2022 then please upgrade to the most recent LTS so you get HDRP 14.0.4+.

👇 Things you should know 👇 (Read this before you buy):

⚠️ Amplify Shader Editor (v1.9.7.1+) is REQUIRED if you want to edit the shader graph.

⚠️ WebGL is NOT supported

⚠️ VR is NOT supported (tested on Oculus 3) - It's under investigation.

⚠️ This is for the HDRP ONLY. It does not support URP or the Built-In renderer!

⚠️ This is NOT a VOLUMETRIC CLOUD (ray marching) or weather system. In order for the (experimental) cloud intersection system to work you will have to add some prefabs to your camera and your clouds. Setup tutorial in the manual. It's just one script and two clicks.

NOTICE: The intersection system only works as RUNTIME in the GAME VIEW, not the editor scene view. Just some heads up.

⚠️ Unity 2022.3 or higher is required (LTS releases strongly recommended).

✍️ Usage

1. Look for cloud prefabs in the Assets/Kamgam/SkyCloudsHDRP/Runtime/Prefabs folder or simpy use the SkyClouds shader on your own meshes.
2. If you want to have camera/cloud intersection color fading the add the CloudObserver script to your camera and follow the setup guide in the tutorial (don't forget to also add colliders and SkyCloud scripts to your clouds).
3. Done, no more setup is needed.

😎 HINT 1:

There are shader variations available with improved tessellation (for very big clouds) and no tessellation (for low-end mobile devices).

🧐 HINT 2:

Check out the shader in the Amplify Editor, you can tweak the tessellation there.

🤠 HINT 3:

There are a lot of paramters for this shader. Use them to customize your clouds (details in the manual).

😎 Hint 4:

For cloud mesh generation I'd recommend the excellent Mud Bun tool (am not affiliated with the creator in any way, just think it's a really nice fit here).
