Question: OSG have only running in SingleThreaded mode in Qt?

[ChenKe404]

if 'yes', it's mean I can't use MultiThreaded mode?
Is 'yes' for both Qt5 and Qt6?

[CapTainHbb]

i think your answer is 'yes'. OSG runs in single-threaded mode with Qt and you can't set the multi-threaded mode in OSG (it causes run-time or complie-time error in multi-threaded mode).
in our project we had the issue that OSG only runs in single-threaded mode in Qt and our solution was to separate Qt and OSG application in two processes and make the connection between them with zmq. but it caused a lot of extra work to set connection between them properly.
