Description

Fix pass() build during sample() call using Mesh.

// material
const material = new THREE.NodeMaterial();

const maskScenePass = pass( maskScene, camera );

material.colorNode = Fn( () => {

	const maskTexture = maskScenePass.getTextureNode();

	const maskVal = maskTexture.sample( screenUV ).r

	return mix( color( 1, 0, 0 ), color( 0, 1, 0 ), maskVal );

} )();

// mesh
mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
