Question: Is there a Unity-compatible tool that can help me quickly generate high-quality, 8K resolution skyboxes for my project?

If you need a Unity-compatible tool to create high-quality, 8K resolution skyboxes fast, Blockade Labs has Skybox AI, a next-gen tool that uses AI to generate 360° panoramic worlds. The tool is useful in particular with its Text-to-Skybox feature, which can create unique skyboxes in seconds based on text prompts. It also has Prompt Enhancer, Negative Text and Styles (48 art styles) to refine results. The Remix feature can change visual styles, time of day, weather and other factors, so it's a good option for game developers and content creators.

Another good option is Scenario, an AI tool to help game developers quickly create high-quality, style-consistent game assets. It can handle a range of workflows and game engines, including Unity, and offers advanced control and customization options like Composition Control and Pixel-Perfect Inpainting. It's good for speeding up game development, ensuring consistency across different aspects of game development and delivering a better gaming experience.

For a more general-purpose tool, Skyglass lets you create 360-degree AI-generated backgrounds in real-time with Unreal Engine technology. Although geared primarily for video creation, it can be used for game development with features like custom Unreal Engine environment imports and high-quality exports. It's good for content creators and pros who need to generate dynamic environments fast.
