Screen space decal (Deffered decal)

Unfortunately deferred decals do not work with a forward rendered like babylon.js. It only works with deferred engines

Maybe you can have a look at how we build the decals to see if you can tweak it to adapt to your needs?

BabylonJS/Babylon.js/blob/master/src/Meshes/Builders/decalBuilder.ts#L40


 * * The parameter `size` (Vector3, default `(1, 1, 1)`) sets the decal scaling

 * * The parameter `angle` (float in radian, default 0) sets the angle to rotate the decal

 * @param name defines the name of the mesh

 * @param sourceMesh defines the mesh where the decal must be applied

 * @param options defines the options used to create the mesh

 * @param scene defines the hosting scene

 * @returns the decal mesh

 * @see https://doc.babylonjs.com/how_to/decals

public static CreateDecal(name: string, sourceMesh: AbstractMesh, options: { position?: Vector3, normal?: Vector3, size?: Vector3, angle?: number }): Mesh {

    var indices = <IndicesArray>sourceMesh.getIndices();

    var positions = sourceMesh.getVerticesData(VertexBuffer.PositionKind);

    var normals = sourceMesh.getVerticesData(VertexBuffer.NormalKind);

    var position = options.position || Vector3.Zero();

    var normal = options.normal || Vector3.Up();

    var size = options.size || Vector3.One();

    var angle = options.angle || 0;



    // Getting correct rotation

    if (!normal) {

        var target = new Vector3(0, 0, 1);
