✅Make your game look great

Our realistic skybox helps your environment attract and immerse players. This kit has everything you need to make your world an immersive environment.

The dramatic clouds move and animate. They respond to the time of day with dynamic lighting. Transition from cloudy atmospheres to desert skies in seconds. Our beautiful cloud renderer looks amazing.

✅Atmospheric Fog and Real-Time Lighting

Our interactive clouds blend into the atmospheric fog. They incorporate direct lighting from the sun and cast shadows. And they use our real-time ambient lighting to match your environment.

✅Fly Through the Clouds

You control whether you render the clouds in the background or as part of your environment. Whether you are flying, climbing, or looking up from the ground, these clouds look great. Imagine the view, the expanse, when you climb to the mountaintop and look down on the clouds.

✅Day Night Cycle

The entire sky changes over time. Our day night cycle transitions from daytime to nighttime. All part of our daytime simulation that you control. The procedural skybox works.

Sun and Moon

Celestial bodies, like the sun and moon, animate across the sky. All part of a realistic astronomical simulation. At nighttime, watch as the stars come out. And the starry sky illuminates your world.

✅Immersive Environments

Are you building a stylized, realistic, pixel art, or low poly game? Our dynamic sky will make your immersive environments stand out.

Are you making a fantasy, horror, medieval, RPG, JRPG, or sci fi project? Build new gameplay elements with our interactive clouds and time of day system.

✅Animated Cloud System

Forget about a boring static skybox generator or flat skybox textures. With a skybox pack, your game will never feel immersive. Your players will never feel like they are in nature. Instead, use Altos to create a believable atmos, and players will love your game.

✅Weather Simulation

Help your game come to life with our integrated weather simulation. Clouds zip across the sky. Our lightweight weather simulation sells your dynamic sky. Or, you can take weather control with a configurable Weathermap. Want your volumetric clouds in the shape of a flying star? If you can dream it, you can make it.

✅Great for low poly, stylized, and realistic projects

This sky is perfect for all environments. Are you are making a Japanese medieval RPG? A stylized lowpoly game set in the stars? A pixel art world set at night in the jungle? This is the skybox renderer for you. It looks great.

✅Dynamic Skybox

Our skybox package is a procedural sky with dynamic lighting. Sit back and watch animated clouds, skies, suns, moons, and stars move overhead.

Achieve the ultimate skybox customization. Make the most beautiful scenic skies.

✅Compatible and Performant

Our optimized, game ready procedural sky system has got your back. Designed with excessive quality and care. Your players will think you're using HDRP or Unreal Engine.

We know that performance is important. That's why we designed our sky to be fast.

✅Compatible with Water and Vegetation

Altos is compatible with water and vegetation, too. Whether your game is set in the ocean or in the forest, this skybox toolkit is for you.

✅Compatible with VFX

Our skybox package is also compatible with VFX. If your fantasy wizard casts a magical spell, it'll look right.

✅Optimized

You are in control. This asset is optimized. It is super quick. And you can make it even faster.

Forget about using a skybox editor. Everything you need is right here. Quality, optimized, game ready.
