Object is still referenced by renderItems in WebGLRenderList, after it is removed from scene.

After an object was removed from scene, it is still referenced by renderItems. I clear renderItems as below. But the object may be referenced by opaque or transparent. Once I clear opaque and transparent, nothing is rendered(only background color)! I don't how to get it fixed. Could you please double check if the original code is correct and if not how to fix it?

`function WebGLRenderList() {

	var renderItems = [];
	var renderItemsIndex = 0;

	var opaque = [];
	var transparent = [];

	function init() {

		renderItemsIndex = 0;
		opaque.length = 0;
		transparent.length = 0;

		# renderItems = [];
	}`

I do not understand what your problem is. You have not explain what you are doing, what happens and how it differs from your expectations.

The code you have provided does not help to clarify this situation for me.

Please consider editing your post.

Usnul, in my project, threejs objects will be added to and removed from scene frequently. Once I remove them from scene, I suppose that they should be not referenced by THREE. But when I use Chrome dev tool to take a snapshot, I found "renderItems" still kept some of them.

The above code only assigns zero to renderItemsIndex, but doesn't make renderItems empty. I think it causes the "memory leak".
