Custom material doesn’t work

[CE87]

Hello! :)

I'm trying to create a custom material (QMaterial) that has a fragment shader code. Like so (code not complete):

class MyMaterial(Qt3DRender.QMaterial):
    def __init__(self, parent = None):
        program = Qt3DRender.QShaderProgram(self)
        program.setVertexShaderCode(Qt3DRender.QShaderProgram.loadSource(QUrl("qrc:/shader.vert")))
        program.setFragmentShaderCode(Qt3DRender.QShaderProgram.loadSource(QUrl("qrc:/shader.frag")))

        ...

        self.setEffect(effect)

But if I add this component to an entity nothing is rendered:

myMaterial = MyMaterial()

sphereEntity.addComponent(sphereMesh)
sphereEntity.addComponent(sphereTransform)
sphereEntity.addComponent(myMaterial)

It should work.

I’m afraid there are no bindings for this yet. Does anyone have a working example or work around?
