Instances performance

[Adem]

Hy guys, i used instances for my mesh, but it's really laggy

Here's the code:

var house;
BABYLON.SceneLoader.ImportMesh("Cottage_House", "cottage/", "cottage.babylon", scene, function (newMeshes, particleSystems, skeletons) {
  house = newMeshes[0];
house.scaling = new BABYLON.Vector3(0.09, 0.09, 0.09);
house.position = new BABYLON.Vector3(-6, 0, 0);
house.checkCollisions = true;
var instances = new Array();
    for (var i = 0; i < 10; i++) {
        instances = house.clone('Instance' + i);
        
instances.position.z = 4;    
instances.position.x = 3;    
    }
    var houses = BABYLON.Mesh.MergeMeshes(instances);

Try instead of mesh clone do new Mesh.createInsance() I think it is to make an instance instead of a clone to save the draw calls.

If he was merging the meshes, which seems to be the case, it should be reduced to one draw call (assuming one house was one draw call).

Try to look at the browsers' profiler to see which functions are the slowest.

thanks ,  it's just working fine

@Pryme8Is this code correct?

var instances = new Array();
    for (var i = 0; i < 8; i++) {
        instances = house.createInstance('Instance' + i);

instances.position.z = 4;    
instances.position.x = 3;    
    }
    var houses = BABYLON.Mesh.MergeMeshes(instances);

InstancedMeshes shouldn't be merged.

oh i corrected that, thanks
