I have some problem when I serialize a terrain. then the serialized data is not reloaded with ImportMesh. As soon as there is a texture on the ground, the serialization it passes bad. The only time it works is when a texture is not added. For exemple : With no material : If I take the case of a simple ground with CreateGround()  it will work (Because no textures are added here) . But if I create now with CreateGroundFromHeightMap() it will not work (Here we add a texture) htt
