Research direction

Start with the jme3-plugins glTF loading path and the CustomContentManager warning shown in the issue. Read the EXT_lights_image_based specification and inspect the EnvironmentTest glTF-IBL assets; done means those assets load with the extension supported rather than producing an unknown-extension warning.

Written by the indexing model from the issue text.

Description

enhancement

Adobe and Microsoft have specified an extension to glTF for cubemap-based lighting.

Currently, attempting to load such assets causes warnings:

Mar 13, 2024 10:59:16 PM com.jme3.scene.plugins.gltf.CustomContentManager readExtension
WARNING: Could not find loader for extension EXT_lights_image_based

Since the extension may be widely used in the future, it would be nice if jme3-plugins fully supported it.

For examples, see EnvironmentTest in the glTF-Sample-Assets repo at GitHub.
