<div dir="ltr">Hmm... it definitely seems to alternate between picking the plane, and not picking the plane. I wonder if the picking issue might be related to the rendering somehow.

Thanks for the help.<br>

So here is the added LOG:<br>

Starting from y = 480 i'm on on the plane anymore so I just get the log<br>
staying that I'm outside of it.<br></blockquote></div></div></div>
