Overlay mesh is transparent for certain material colors in Forge 3D viewer
问题 I'm trying to add custom geometry to my forge viewer, following this example. It mostly works fine, except when using certain colors. I'm using the following code to add a sphere mesh: const geometry = new THREE.SphereGeometry(0.4, 32, 32) const material = new THREE.MeshBasicMaterial({ color: someColor, transparent: false, }) const sphere = new THREE.Mesh(geometry, material) viewer.overlays.addScene('sphere-mesh-scene') viewer.overlays.addMesh(sphere, 'sphere-mesh-scene') for certain values
