I'm simuating fire by using a video texture. (see: https://blender.stackexchange.com/a/80954/6102 ) This works fine on my pc.
Now if I try to render on a different pc (I have tested 3 different pc's) I get each time a sqhare instead of a nice explosion (where you only see the explosion from the video instead of the full rectangle of the texture being rendered).
The result should be a nice explosion (which I have on my other pc: https://i.stack.imgur.com/o3gw9.gif )
Any idea what is wrong? I'm using the latest blender version (2.78c)
and GPU compute with feature set supported is active.
My blender files also have "External data" -> "Automatically pack into .blend file" enabled, so the video texture should be enabled.
Update: this is a test file which works fine on my pc (shows the explosion nicely) but on the other pc's it shows just some kind of white rectangle.
