qt 3d Qml Transparent Scene2D texture
2
How to render mesh texture, without this default, grey background? I mean, use Scene2D component, to generate texture with alpha. Now it's look like there was PhonMaterial underneath my red rectangle.
Entity
id: root
components: [cubeTransform, cubeMaterial, cubeMesh]
PlaneMesh
id: cubeMesh
width: 10
height: 10
Transform
id: cubeTransform
translation: Qt.vector3d(0, 4, 0)
scale3D: Qt.vector3d(1, 1, 1)
TextureMaterial
id: cubeMaterial
texture: textureId
Scene2D
id: qmlTexture
output: RenderTargetOutput
attachmentPoint: RenderTargetOutput.Color0
texture: Texture2D
id: textureId
width: 100
height: 1024
format: Texture.RGBA8_UNorm
generateMipMaps: true
magnificationFilter: Texture.Linear
minificationFilter: Texture.LinearMipMapLinear
wrapMode
x: WrapMode.ClampToEdge
y: WrapMode.ClampToEdge
Rectangle
x: 50
width: 50
height: textureId.height
color: "red"
Now, half of the mesh is red (as it should), but the second one is white, rather than transparent.

It's difficult to tell from the code snippet you posted what is wrong. Please always post a minimally working example.

When I try to run your example it says "No renderer settings component found". Also the import statements are missing.

Have you tried to use alpha in the Rectangle color ? Like color: Qt.rgba(1, 0, 0, 0.5)

Have you tried to use alpha in the Rectangle color ? Like color: Qt.rgba(1, 0, 0, 0.5)
