getHeightAtCoordinates not work with ImportMesh

[Dad72]

Hello,

I have a ground serialize with SerializeMesh() that I save in a babylon file. When I reload this file with ImportMesh:  getHeightAtCoordinates, updateCoordinateHeights, optimize ... does not work.  In fact everything concerning the ground create with CreateGroundFromHeightMap() or CreateGround() is serialized as mesh but can no longer be used as a terrain. We can only edit the properties on the mesh and not the geometry that no longer exists after serialization.

May be missing a serialization for the ground, like serialiserGround() in addition to serializeMesh(). Or convert a mesh to ground after using ImportMesh for used getHeightAtCoordinates. 

Thanks DK

I think that a de-serialized mesh is just a mesh, not a groundMesh.

Maybe is there an elegant way in JS to give to the deserialized mesh all the groundMesh methods ?

something like :

deserializedGround.prototype = BABYLON.GroundMesh.prototype;

Dunno ...

Jerome is right. A groundMesh is deserialized as a regular mesh. If someone wants to step in to add this option (should not be too difficult) I'll be happy to review the PR

I would be delighted to offer a PR, but I do not know what to change to add or make this option. Maybe @jerome knows what to do to add this and make a PR.

no idea, sorry.

You said something like that, but I do not understand

[Dad72]

I think I understood nothing. When I do this, it does not work.

newMeshes[0].prototype = BABYLON.GroundMesh.prototype;
newMeshes[0].updateCoordinateHeights();

If Jerome says has no idea, I think it's difficult. I do not even know what file to edit and what to add.

I don't really know how to make typescript class inheritance in javascript actually

Imho, the right way would be to make the de-serialized mesh inherit from the GroundMesh class.

[Dad72]

I can not find a solution for that.

Well, I will change my method of creation and save for the terrain. ImportMesh does not load a terrain and serializeMesh, does not serialize a terrain.
