SpecularGlossiness model is not displayed correctly

[cx20]

I tried to display SpecGlossVsMetalRough.gltf using the latest version of Ashes.

However, the SpecularGlossiness model does not seem to be displayed correctly.

This is a known issue, Ashes doesn't support any extensions yet.

FYI: You can use HDR environment textures in the latest version.
Usage:

let assetRoot = 'https://but0n.github.io/Ashes/
let specEnv = await Asset.loadCubemap(assetRoot + 'res/envmap/helipad/', 'hdr');
let diffEnv = await Asset.loadCubemap(assetRoot + 'res/envmap/helipad_diff/', 'hdr');
let gltfroot = scene.appendChild(await Asset.loadGLTF(gltf, screen, specEnv, diffEnv));
