cannot read property 'slice' of undefined when converting ground to flatShadedMesh

[alanz2223]

I am creating a new ground from a height map and would like to convert it to a flat shaded mesh, however I am receiving an error when calling the mesh's convertToFlatShadedMesh(). 

Cannot read property 'slice' of undefined.

and what is undefined is the mesh's subMeshes property.

relevant code is simple

 

var plane = new b.Mesh.CreateGroundFromHeightMap('plane', 'map.png', 100, 100, 50, -5, 5, scene);   
        
plane.convertToFlatShadedMesh();

Maybe try assigning a material before converting.

It does not work, I dont think that the material would be modifying with the subMeshes anyways. if you would like to see it for yourself the playground demo height map does the exact same thing when you call ground.convertToFlatShadedMesh();

This is because the ground mesh is created asynchronously (it needs to read the texture first).

 

Just use the onready callback : http://doc.babylonjs.com/classes/2.3/Mesh#static-creategroundfromheightmap-name-url-width-height-subdivisions-minheight-maxheight-scene-updatable-onready-rarr-groundmesh-classes-2-3-groundmesh-

Yes this did the trick, thanks.

Delta beat me to it  yup, because the ground has to be constructed first for the uv to take effect the material has to be called on the onready call back, because otherwise it does not exsist yet or is fragmented.
