Hi, This is a user forum, you should check the bug report system to see if there's something related there. In any case, it's always better to add the version of Qt you are using as well as the platform you are running on. And in the case of a module like this one, the peripherals you are using.

@J.Hilk thank you @J-Hilk ... this one working for me...

@SGaist yup now i solve the issue Thank you

How were you able to load an FBX after including Autodesk FBX SDK?

You can access the uniforms with the parameter classes. So for example: auto boneId = new Qt3DRender::QParameter(); boneId->setName("uBoneId"); boneId->setValue(QVariant(1)); customMaterial->addParameter(boneId);

Hi and welcome to devnet, Can you explain in what way it's related to Qt ?

@ambershark sorry I mean the single-player RPG. Thanks for your advise.

Thanks for your suggestion, I prefer QT5 and 3D studio more. It is a lot of work refer to several modules. QT4 load FBX maybe more difficult。 I have to learn FBX SDK and opengl ,too bad

Since you're a designer, QtQuick will likely be the fastest way to get something up and running without too much pain.

Hi and welcome to devnet, What exactly are you asking for ?

@DPixel please don't forget to mark your post as solved! Thanks

@amarism said in How to connect signal and slot in different classes in Qt: location 0xFFFFFFFFFFFFFFFF. That's definitely a pointer error that doesn't have anything directly to do with signals or slots. What you really want to do is read the documentation on the QtCreator debugger so you can understand which variable has that invalid address 0xFFFFFFFFFFFFFFFF, and rework your logic. That sort of error message indicates that any function you tried to use on or in that object would explode badly, not just the connect(). Because you are focused on the signals/slots that you are trying to accomplish, you may be "missing the forest for the trees" in trying to find a solution.

Hi and welcome to devnet, What version of Qt are you using ? On what platform ? How did you install it ? In Qt 5, QGLWidget has been deprecated in favour of QOpenGLWidget. Also depending now what you want to do a QWindow might be a better starting point.

@SGaist Border around the widget after mouse clicking? After removing the mouse move code my output comes like this and when i will press after the widget 1. it will change to normal form. [image: e38154dd-a681-4d05-85c9-4cd6b0675cdb.jpg]
