[solved]how to multiple babylon file load ??

[MinsuKim]

hi

as always

one problem T.T

 

issue is how to multiple *.babylon file load?

i have 16 files

one file has 31box create by 3DMAX

 

my code is below

for (let i = 0; i < resourceCount; i++) {

onLoadImage();

}

 

function onLoadImageFileT() {

 

   BABYLON.SceneLoader.AppendAsync(strResourceURL, fileName, scene, function (newScene) {

 

   newScene.executeWhenReady(function () {

 

   let loadMesh = newScene.getMeshByName("resoucreName");

   scene.lights[1].dispose();

   loadMesh.position = new BABYLON.Vector3(machineForLayout.mPositionX, machineForLayout.mPositionY, machineForLayout.mPositionZ);

   loadMesh.scaling = new BABYLON.Vector3(0.035, 0.035, 0.035);

   loadMesh.rotation.y = machineForLayout.mRotationY;

   loadMesh.name = "Machine#" + machineForLayout.mMachineId;

   loadMesh.id = "Machine#" + machineForLayout.mMachineId;

   loadMesh.isPickable = true;

   });

 

   }, function (progress) {

   // To do: give progress feedback to user

   }, function (error) {

   console.log(error);

   });

 

}

 

problem is 12file load is OK

but 15 file over is "Too many active WebGL contexts. Oldest context will be lost."

i do not understand message..

i many search and try other code... but same issue

(assetmanager, importMesh, Append)

 

please help me

It seems that you are creating a new Engine per file. Can you share the entire code? Or reproduce the problem in the Playground?

@Deltakosh  hi my Star!

 

new engine per file not correct.

 

var engine = new BABYON.Engine();    i think it is one time call because private member variable

i'm not try playground and shared.. T.T (*.babylon file is our company equipment modeling )

have you tried with BABYLON.SceneLoader.Append  instead of BABYLON.SceneLoader.AppendAsync  just to test that.

For some attempts in this topic

I made a project that loads more than 16 fileshttps://happy-hamilton-38ec27.netlify.com/workercoreblocks22

code here https://github.com/BabylonJSGuide/largemaps/blob/master/workerCoreBlocks22.html

It might give you some help (or not) ?

@Dad72  i tried   BABYLON.SceneLoader.Append  instead of BABYLON.SceneLoader.AppendAsync 

but same thing

thank you for reply!

 

@JohnK you code is good  I have updated my code by comparison.

thank you for reply!

 

@Deltakosh you correct! 

my code some changed!

this problem is solved

but I do not know how it was resolved.

BABYLON.Engine.isSupported() Issue...????  don't know ㅇ_ㅇ....

 

Thank you to everyone who helped me.

see you later with other Issue! lol

 

my code below

before

for (let i = 0; i < machineCount; i++) {

 

     if (BABYLON.Engine.isSupported()) {

         onLoadImage();

     }

}

 

after

for (let i = 0; i < machineCount; i++) {

     onLoadImage();

}

perfect! ANd you are right IsSupported will create a temp canvas so it is a good idea to call it only once
