How to Access Unity3D to BabylonJS's ShadowGeneratorList

[JBlack_UTD]

Hello,

I'd like to access the babylonScene.ShadowGeneratorsList that SceneBuilder.Lights.cs uses, but I can't seem to find any variable that doesn't come up as undefined after I've called the SceneLoader.Load

private void GenerateShadowsGenerator(Light light)
        {
            var generator = new BabylonShadowGenerator
            {
                lightId = GetID(light.gameObject),
                usePoissonSampling = light.shadows == LightShadows.Soft,
                mapSize = 256 + 256 * QualitySettings.GetQualityLevel(),
                bias = light.shadowBias / 10.0f,
                useBlurVarianceShadowMap = light.shadows == LightShadows.Soft
            };

            var renderList = new List<string>();
            foreach (var gameObject in gameObjects)
            {
                //why not deliver the boolean to the scene? I could use that boolean to manually create shadows inside babylon.
                var meshFilter = gameObject.GetComponent<MeshFilter>();
                var renderer = gameObject.GetComponent<Renderer>();
                if (meshFilter != null && renderer.shadowCastingMode != ShadowCastingMode.Off)
                {
                    renderList.Add(GetID(gameObject));
                    continue;
                }

                var skinnedMesh = gameObject.GetComponent<SkinnedMeshRenderer>();
                if (skinnedMesh != null && renderer.shadowCastingMode != ShadowCastingMode.Off)
                {
                    renderList.Add(GetID(gameObject));
                }
            }

            generator.renderList = renderList.ToArray();

            babylonScene.ShadowGeneratorsList.Add(generator); //***How do i access this list in babylon?***
        }

The end goal here would be to emulate the Unity mesh renderer option to cast shadows or not. The exporter does this, but if I can't access the shadow generator list, I can't determine which meshes to push into the wanted shadow generators.

That's my understanding of the problem at least.

As an aside, I've created shadow generators for two point lights (manually), and I'm importing one spot light which I've positively determined has a shadow generator created for it somewhere.

The only thing left I have to do is determine which meshes can cast shadows, and then push those meshes into the shadow generator render lists.

Thank you for your time.

Hello,

there is no shadow generator list generated at loading time but you can go through all lights and check for light.getShadowGenerator()

[JBlack_UTD]

That seems to have done the trick! Thanks.

for (var i = 0; i < newScene.lights.length; i++){

    if(newScene.lights[i].getShadowGenerator()){
      console.log("dingdingding.");
      newScene.meshes.forEach(function(mesh) {
        newScene.lights[i].getShadowGenerator().getShadowMap().renderList.push(mesh);
      });
      continue;
    }
    ...
}
