I cannot understand PBRInstancedMaterial. Is it a simple shader to replace lightEntity? Is there a simply way to set Env Light such as "lightEntity = new Qt3DCore::QEntity(camera())"? I saw the color information has been transferred to Klein::ConcretePointsRenderer/Klein::ConcreteLinesRenderer, and so each geometry owns its material. Thanks!

// Add PBR material
auto pointsMaterial = new Klein::PBRInstancedMaterial(rootEntity);
pointsMaterial->setUseInstanceColor(true);
pointsMaterial->setRoughness(1.0f);
pointsMaterial->setMetalness(0.0f);
pointsMaterial->setEnvLightBrdf(brdfMap);
pointsMaterial->setEnvLightIntensity(1.0f);

Would you like to provide one example of selection and removing?

How to (1）set orth-camera? if camera()->lens()->setProjectionType(Qt3DRender::QCameraLens::OrthographicProjection)， the mouse does not work. (2) how to set a phong shader? (3) draw one 2d-rectangle with mouse for selection ?
