<p dir="auto">It looks like when using the JSONLoader in r74, the first named bone in an exported Maya scene gets a duplicate of all the geometry.</p>
<p dir="auto">Here's a <a href="https://jsfiddle.net/evantron3000/1j5xwhbf/" rel="nofollow">JSFiddle</a> that shows my current code and the issue.</p>
<p dir="auto">In this example I have 2 boxes. Each box is bound to a single bone, and each of those bones has keyframes that animate the position and rotation. There is another bone that has no geometry bound to it, and has keyframes that make no change to its position or rotation.</p>
<p dir="auto">The stationary bone is called "joint1" in Maya. The bones that actually have geometry bound to them are called "joint2" and "joint3". If I were to rename the stationary bone "joint4" the result would be a duplicate of both boxes attached to the currently animating "joint2".</p>
<p dir="auto"><strong>Is your feature request related to a problem? Please describe.</strong></p>
<p dir="auto">It would be nice to have HDR environment maps mapped onto flat planes or circles that are flatted near the bottom centre.</p>
<p dir="auto"><strong>Describe the solution you'd like</strong></p>
<p dir="auto">It should be possible to set a vertical ground height and also a bias parameter that determines how much the sphere is flatted to this ground plane.</p>
