Vertex Buffer error

[MLB]

Something with the vertex buffer is failing.
My script uses GPU instances. Please HELP

Best guess - this is how the instancing vertex buffer needs to be created - note the second parameter:

const vertexBuffer = new pc.VertexBuffer(
    app.graphicsDevice,
    pc.VertexFormat.getDefaultInstancingFormat(app.graphicsDevice),
    instanceCount,
    pc.BUFFER_STATIC,
    matrices
);

I have done what you suggest, now I receive this error

[mvaligursky]

see line above in your code … that’s how you access the graphics device.

Ok, I already solved, thanks for the rapid help

    const vertexBuffer1 = new pc.VertexBuffer(
        this.app.graphicsDevice,
        pc.VertexFormat.getDefaultInstancingFormat(this.app.graphicsDevice),
        instanceCount,
        pc.BUFFER_STATIC,
        matrices
    );
