Exploding GLB Model Files

rdurnin · May 19, 2021, 5:56pm

Hey guys, and I am looking into an issue which appeared over night with loading GLB models. The issue is an unusual one, as I have not touched the code related to loading files in a few days, and the LoadAssetContainerAsync function is completing and returning a container. I am working on building a useful case, but I am hoping that the error might be familiar to any of you.

Some ms after the LoadAssetContainer’s then call to console.log, I get the following error messages:

The scene contains two sphere models, and no textures. Scenes containing only cameras, have no problems to load.

(Pardon me for the long string):

I upgraded recently to support some additional extensions, but was able to work without issue for some time after.

@babylonjs/core@5.0.0-alpha.22
@babylonjs/loaders@5.0.0-alpha.22

After some debugging I have located more clearly the source of the error:

In postProcessManager.ts there is a call to: engine._debugInsertMarker, which exists on ThinEngine but not the Engine instance available at scene creation time (prototype). Tracing backwards, it is being called during the creation of PBRMaterials when environment textures are generated (and call PostProcessManager.directRender). Commenting the line out returns functionality as expected.

The function is being added through engine.debugging.js, although it is not clear to me why it is missing from the engine prototype I am using. The engine is being created using the following calls:

const canvas = document.getElementById(“render-canvas”) as HTMLCanvasElement;
const engine = new Engine(canvas, true, {}, true);

None of these parts of the code have changed in months, and I have been using CreateSceneModule throughout to create scenes directly from the engine.

Pardon me, but that call fails everywhere it is being made.

I think you are using tree shaking? This PR should fix the problem:

rdurnin · May 20, 2021, 1:00pm

I am using tree shaking, and thanks Evgeni.

Hey @Evgeni_Popov , and I have installed 5.0.0-alpha.24 which solves the issue as you expected. Thanks.

I am getting an error with the following code in defaultRenderingPipeline and am wondering if it is also being caused by tree shaking:

this._scene.enableDepthRenderer is not a function

Is it possible that this is being stripped out? I am enabling depthOfField from a json object which contains render settings, and it not being called in the code elsewhere.

Evgeni_Popov · June 3, 2021, 5:03pm

I think you should import rendering/depthRendererSceneComponent. See Babylon.js ES6 support with Tree Shaking | Babylon.js Documentation

Thanks.
