Hi iintegrator,

have you checked that this line of code is present in the _onQCARInitializedNative function (VideoPlayback.cpp):

QCAR::setHint( HINT_MAX_SIMULTANEOUS_IMAGE_TARGETS, 2 );

?

The maximum number of targets

The maximum number of targets that can be active at runtime is 100. These may be in a single device database, or distributed across multiple active device databases.

Hi, the SDK should be able to

Hi, the SDK should be able to handle up to 10 simultaneous targets in the same field of view; at worst I would expect that some of the targets are occasionally not detected when you go beyond 5, but a crash is not expected in such situation.
