In Video3DScene add the following line above line 78… BitmapMaterial.AUTO_MIP_MAPPING = false; and change the following… screen.addCollada(”screen.dae”, materials); to screen.addChild(new Collada(”screen.dae”, materials)); ...it i still video on my mesh pls help I had same problem as david but even after following instructions…

In Video3DScene add the following line above line 78…

…it i still video on my mesh

pls help

I would guess that you just need to make sure the Bitmap object and Papervision are allowing (setup properly) the transparency. Unfortunately I've had problems with audio syncing too. I've had a better experience with streaming the video. There are security restrictions around capturing RTMP content so you have to hack around these. I did this by using a Flash 8 SWF which loads and streams the FLV and then loading this SWF into my FP9 / Papervision app. However, this may not work in the latest versions of the player.

I've set the bitmapData transparency switch to true and color to 0x00FFFFFF, The video and transparency do work, but each frames "stays" on the surface as if it were painted on (Lets say "a dot passing by would draw a line") I need to know if there's a workaround for this 2. Also the video and sound are completely off-sync. Obviously the video is slowed down but the sound plays to its correct speed. Any idea to fix this? I suppose the video resolution is for something (1080x608) but when used "normally" without PV3D, it plays well. Is using a plain instead of a collada mesh would help? Thanks, Olivier Clément Hi,

I had a look and there is a pretty simple fix that should get things up and running again. In Video3DScene add the following line above line 78... BitmapMaterial.AUTO_MIP_MAPPING = false; and change the following... screen.addCollada("screen.dae", materials); to screen.addChild(new Collada("screen.dae", materials)); Hope that helps. Hi David,

Is there an obvious change that I need to make to the code? I haven't been able to find it. Thanks! David Hi Paul,

Security restrictions in the Flash Player won't allow you to grab a bitmap capture of RTMP content. See the note about it in the live docs, http://tinyurl.com/38rsoe. There are some work arounds but I wouldn't count on them to work in the future. Unfortunately, the best you can do is embed the FLV into a SWF for now and hope Adobe changes its security policy on the matter. If that's not the cause of the issue... Not sure what is. I've never had any problems beyond the security restrictions. Are you streaming the FLV? Security restrictions in the Flash Player won’t allow you to grab a bitmap capture of RTMP content.

I'm trying to figure out why my video-on-3d freezes. Is there a place where one can look for exceptions? I don't get anything out of the debug standalone viewer when the video freezes.
