Corona 14 includes AI tools, such as the AI Material Generator (which turns images into PBR materials) and the AI Enhancer (which improves the appearance of people and vegetation) and some more. If you prefer not to use them, you can easily disable all AI features by adjusting a single system setting.
What Gets Disabled
When you disable AI features, the following tools will be turned off or hidden:
AI Material Generator – The Chaos Cosmos tool that creates materials from images will be disabled.
CMasking_AiEnhancer Render Element – This special render pass will be unavailable.
Enhance Button – The AI Enhancer button in the Virtual Frame Buffer (VFB) will be disabled.
Enhance for VFB History Images – The AI enhance feature for saved history images will no longer be available.
Note: disabling AI features disables them for all Chaos products, not just Corona!
