01

REALITYKIT
VIEWPORT

Preview your scenes in real time with a RealityKit-powered viewport. Orbit, pan, and inspect your model exactly as it will appear on Apple platforms, with accurate lighting and material rendering.

02

ENVIRONMENT
LIGHTING

Evaluate your materials under real-world conditions using a curated collection of IBL environments: Neutral, Beach Sunset, Downtown Night, Neighborhood Overcast, Rooftop Sunny, and more. Adjust exposure and rotation, toggle soft reflections, or use the environment as the scene background.

03

MATERIAL
EDITOR

Tweak materials per scene with full control over the conversion output. When editing, choose to keep your materials as-is or convert to USD Preview Surface or MaterialX. The conversion applies as you edit, so what you see is what gets exported. Review and adjust Base Color, Metallic, Roughness, Emissive, and Opacity, and replace or clear individual textures per channel.

04

TEXTURE
OPTIMIZATION

Optimize textures per channel to reduce your final USDZ file size. Choose from JPEG, PNG, or AVIF output, set quality (Fast, Balanced, or Best) and maximum resolution, and generate mipmaps for smoother RealityKit loading.
