Hello again guys
so u find here my station (quasi-completed) made by blender: https://playground.babylonjs.com/#KI8BJH#20
now I want to do some changes in my stairs (they are inside you can not see them), so I want to “hide” all levels of my station and keep only the stairs, I tried : var level3=scene.getMeshByName(“SketchUp.002”) and then level3.isVisible= false; but here level3 is a node parent (so I should get all the meshes of my level and then hide ).
this is a blender screenshot :
I have a lot of subMeshes is there a way to call them directly.
