Help! Babylon scene too slow

[Rasimus]

I have exported scene from clara.io to babylon.js

and give me a 22353 code lines scene.

it works, but its too slow.

This is my code:

 

    BABYLON.SceneLoader.Load("mypath", "myscene", engine, function (newScene) {

      newScene.executeWhenReady(function () {

      newScene.activeCamera.attachControl(canvas);

      engine.runRenderLoop(function() {
        newScene.render();
      });


    });
   }, function (progress) {

      });

Do you know some method or something to make it faster ?

Hello,

 

without info about your scene, we cannot help you

 

can you share the statistics produced by debug layer?

[Rasimus]

Run my scene on Babylon sandbox because i canot run my code on playground

i dont know if its because i export my scene from clara

 

this are the stats:

You have wayyyyy too much materials in your scene. As far that I can see, your scene looks like 7 set of similar meshes. Try to use the same materials for all similar meshes.

Another way to improve your performance would be to merge several meshes.

Good luck!

other option could be to use the sceneOptimizer: http://doc.babylonjs.com/tutorials/How_to_use_SceneOptimizer

[Rasimus]

I will try that, thanks a lot.

[davrous]

Yes, the scene optimizer should help you. You have far too much draw calls. You need to merge the objects.

Do you know how to merge the objects, on clara ?

it suposed that all the objects are grouped, its the same that merge ?

[Dad72]

No, group and merger are not the same. You have to weld objects to a single object. 

I do not know clara, I therefore can not help you more.

and you need to reduce the number of polygons of your objects to optimize your sene too.

also use textures 512*512 instead of 1024*1024

[Rasimus]

Oooook ! ill try that

Thanks
