Technical Specs & Naming
Scheme:
WormholeSkies_V1_Sky##_[8K|2K]_[EQR|HDR|EXR|CUBE|CUBE_RBX|GLB|VID-L|VID-P|VID-SQ]GLB: glTF 2.0, unit scale = 1.0, inverted normals, non-overlapping UVs, unlit/emissive material
Bit depth: 8-bit (JPG/PNG), 32-bit (HDR/EXR)
Guidance: Readme includes EV/white-point notes for consistent IBL
Compatibility
DCC: Blender, 3ds Max, Maya, Cinema 4D, Houdini, Substance, Nuke
Engines: Unreal Engine, Unity, Godot, Three.js/WebGL (glTF .glb supported)
Roblox: Use the Roblox cubemap set with a Sky object (GLB not required)
Quick Import Notes
HDRI: Use .EXR in your Sky/Sky Light/HDRI Backdrop for lighting; refresh/bake reflections
GLB Skydome: Import the Skydome_InvertedSphere.glb; ensure Unlit/Emissive shader; assign the included JPG/PNG pano if your DCC doesn’t auto-link; set double-sided or inverted normals as needed
Roblox: Create Sky in Lighting; assign the six face images in the provided order
