[SOLVED] Deploying Qt3D application. Unable to find renderer plugin for opengl

When I run my simple example in debug mode from Qt Creator I see these messages:

Quote:

---

QString::arg: Argument missing: " Max Work Group Size: 1536, 1024, 64\n Max Work Group Count: 65535, 65535, 65535\n Max Invocations: 65535\n Max Shared Memory Size: 1536\n" , 49152 QObject::connect(QOpenGLContext, Unknown): invalid nullptr parameter

My program works fine. And when I switch to Release mode I see the same behavior like above. But I what to make a standalone application for running on another computers without Qt.

I added this dll-files to Release folder:

Quote:

---

platforms/qwindows.dll
libgcc_s_dw2-1.dll
libstdc++-6.dll
libwinpthread-1.dll
Qt5Concurrent.dll
Qt5Core.dll
Qt5Gamepad.dll
Qt5Gui.dll
Qt5Network.dll
Qt53DCore.dll
Qt53DExtras.dll
Qt53DInput.dll
Qt53DLogic.dll
Qt53DRender.dll

But when I try to run Release version from Qt Creator I get this message in console:

Unable to find renderer plugin for opengl
23:00:29: The program has unexpectedly finished.

And I get this exception:

I solved this problem. I copied the folder "renderers/openglrenderer.dll" to the release folder from "C:\Qt\5.15.0\mingw81_32\plugins"

These is a list what you need to move your Qt3D application on another computer. It requires 48 MB
