I have just started investigating migrating my krpano flash vtours to the HTML5 supporting krpano viewer 1.17. I discovered that polygon hotspots are not yet supported, so I added some image hotspots to replace these. I have found that in the viewer the hotspot image vanishes if I zoom in beyond a certain level, and the point this happens depends on how close to the nadir of my scene the hotspot is placed.
My hotspot is defined as follows:
<hotspot name="hsDown" devices="all"
url="skin/uparrow2.png"
ath="210.22" atv="86.43"
zoom="false" distorted="true"
width="70" height="48"
scale="0.3" scale9grid="" scalechildren="false" rotate="0"
rx="0" ry="0" rz="-180"
edge="center" ox="" oy=""
visible="true" enabled="true" usecontentsize="false" handcursor="true" capture="true" children="true" maskchildren="false"
zorder="0"
alpha="1.00" autoalpha="false" blendmode="normal" effect="" smoothing="true" pixelhittest="false"
onhover="showtext(Descend into the depths,HotSpotText)"
onclick="looktohotspot(hsDown,,smooth(100,100,100)); loadpano(LosHoyosPitchBase.xml)"
/>
This hotspot disappears as I try to zoom in towards it. I have to move it up the scene (atv="66.43") to prevent it disappearing. Has anyone else found this and is there a fix? I am seeing this in the Chrome browser on both a Windows Desktop and on my Android tablet.
