Reset of applyDisplacementMap

Questions
1

Hi,

is it possible reset a displacement added with applyDisplacementMap?
Every time I reapply it the mesh gets higher so I guess it’s not an absolute value but a relative one. I tried using a black image to reset but because is relative it has no effect. How can I bring back the ground to the original flat state?

Thanks

I add a function to the mesh after creating it:

const vertices = tiles.getVerticesData(VertexBuffer.PositionKind)
        tiles.resetVertices = () => {
            tiles.setVerticesData(VertexBuffer.PositionKind, vertices, true)
            computeNormals(tiles, true, false)
        }

const computeNormals = async (object, updateable, rightHanded) => {
    let normals = []
    const positions = object.getVerticesData(VertexBuffer.PositionKind)
    const indices = object.getIndices()
    VertexData.ComputeNormals(positions, indices, normals, { useRightHandedSystem: typeof rightHanded !== "undefined" ? rightHanded : true })
    object.setVerticesData(VertexBuffer.NormalKind, normals, typeof updateable !== "undefined" ? updateable : false)
}

That’s a very cool solution, thanks a lot for sharing it :green_heart:
