DiffuseMapMaterial Texture

QKelteseth

Hi all,

I'm trying to add a texture to my mesh but for some reason it wont work. Based on https://doc.qt.io/qt-5/qt3d-materials-renderableentity-qml.html

    RenderableEntity{
        id: bow
        source: "qrc:/assets/models/Bow.obj"
        position: Qt.vector3d(0, 0, 0)
        scale:  1

        material: DiffuseMapMaterial {
            id: material
            diffuse: TextureImage { source: "qrc:/assets/models/texture.png" }
            specular: Qt.rgba( 0.2, 0.2, 0.2, 1.0 )
            shininess: 1.0
        }
}

qrc:/main.qml:50:22: Cannot assign object to property

This makes no sense because according to the documentation:
https://doc.qt.io/qt-5/qml-qt3d-extras-diffusemapmaterial.html#diffuse-prop
it takes a Texture image

    RenderableEntity{
        id: bow
        source: "qrc:/assets/models/Bow.obj"
        position: Qt.vector3d(0, 0, 0)
        scale:  1

        material: DiffuseMapMaterial {
            id: material
            diffuse: "qrc:/assets/models/texture.png" 
            specular: Qt.rgba( 0.2, 0.2, 0.2, 1.0 )
            shininess: 1.0
        }
}

qrc:/main.qml:50:22: Invalid property assignment: unsupported type "Qt3DRender::QAbstractTexture*"

Hi! Something is broken with TextureImage. I've experienced that, too. As a workaround the following worked for me:

TextureLoader {
    id: rectTexture
    source: rectEntity.textureSource
}

NormalDiffuseSpecularMapMaterial {
    id: rectMaterial
    ambient: // ...
    diffuse:  rectTexture
    specular: rectTexture
    normal:   rectTexture
    // ...
}

// ...

components: [ rectMesh, rectMaterial, rectTransform ]

Thanks for the quick reply! What kind of an object is:

source: rectEntity.textureSource

Im not able to find the documentation of TextureLoader :(

    TextureImage { id: ti; source: "qrc:/assets/models/texture.png" }

    TextureLoader {
        id: rectTexture
        ???
    }

    RenderableEntity{
        id: bow
        source: "qrc:/assets/models/Bow.obj"
        position: Qt.vector3d(0, 0, 0)
        scale:  1

        material: DiffuseMapMaterial {
            id: material
            diffuse: rectTexture
            specular: Qt.rgba( 0.2, 0.2, 0.2, 1.0 )
            shininess: 1.0
        }
    }
