This is now fixed. Had some loop that was firing onloadcomplete that was automatically setting all the hotspots alpha value.
This is really weird. I'm using the latest krpano and videoplayer plugin. Somehow I can't hide the hotspot when a scene starts with this code:
Code
<hotspot name="video"
url="plugins/videoplayer.swf"
ath="221.2890678560818" atv="4.822723213168538"
alpha="0"
rx="-4" ry="0.75" rz="-2.241615808518938"
zoom="true"
distorted="true"
width="700" height="566"
scale="0.7161732935202246"
enabled="false"
videourl="%CURRENTXML%/videos/cinzas.flv"
loop="false"
pausedonstart="true"
onvideocomplete="tween(alpha,0,0.5);stop();"
zorder="2"Any ideas? Thanks.
