I want intersectObject mPart_DZ.
But it’s been obscured by an outer layer transparent object mPart_DJKT1 ,
i can’t pick up this object mPart_DZ .

if(!event.clientX && !event.touches){  resolve({status:false, intersectObj:null})}
						const clientX = event.clientX || event.touches[ 0 ].clientX;
						const clientY = event.clientY || event.touches[ 0 ].clientY;

						this.pointer.x = ( clientX / window.innerWidth ) * 2 - 1;
						this.pointer.y = - ( clientY / window.innerHeight ) * 2 + 1;

						this.raycaster.setFromCamera( this.pointer, this.camera );

						const intersects = this.raycaster.intersectObjects( this.modelNodeList, true);

						// intersects.forEach((item:any)=>{
						//     if(item.object.name === 'mPart_DZ') {
						//         alert(1);
						//     }
						//     console.log(item.object.name);
						// })

						if ( intersects.length <= 0 ) {
							resolve({status:false, intersectObj:null})
						}else {
							const intersectObj = intersects[ 0 ].object;
							resolve({status:true, intersectObj:intersectObj});
						}

Don’t forget to apply the second parameter to indicate a recursive test. You have to set it to true.

I’ve set it true，but it’s still not detected ,
So I feel weird.

You can control which objects should be rendered and part of intersections test via layers. Just move the object you want to exclude from the intersection test to layer 1 and let the instance of raycaster use the default layer 0. https://jsfiddle.net/v25xp1mL/1/

I need traverse the hidden object and all of its children’s layers ,
make their layers inconsistent with the camera’s layers.

This will solve my problem .
Thank you very much .
