I want some 3d objects to rotate and for a better look, I need some dynamic shadows, that would be visible on the object.
Can anyone recommend a easy way to do it? It could be iOS or Android.
There are some frameworks that create shadows, but they are too hart do integrate with QCAR.
OK, thanks for the confirmation;
then as I said before, there are chances that it is not supported by your device (e.g. if it is a Tegra-based, like the Unity website mentions);
maybe it would be a good idea to check directly on the Unity 3D forum, as I presume you are not the only one experiencing problems with shadows in Unity on Android device.
