let sp = new Laya.Sprite();
let spn = sp.addComponent(Laya.Spine2DRenderNode);
spn.source = "spine/spineboy-pro.skel";
spn.useFastRender = false;
spn.play("portal", true);
sp.scale(0.3, 0.3);
Laya.stage.addChild(sp);
sp.pos(400 * Math.random(), 600 * Math.random());
}) 3.3.4默认useFastRender 为true,所以显示出错，useFastRender不支持裁剪。spn.useFastRender = false;显示会正常但是效率会下降，需要在表现效果还是效率之间权衡
