Creating a cubemap/skybox from blob url

Questions
1

Hello, I’m trying to create a cubemap from a blob .dds/.env object url. But I want the cubemap to affect the reflective materials while staying invisible to the user. I don’t want it to show up as the environment but I want it to affect the reflective materials.

Hello you can simply set it to the material.reflectionTexture only

I have managed to make it invisible to the user using;

if (this._scene.environmentTexture) {
                this._scene.createDefaultSkybox(
                    this._scene.environmentTexture,
                    true,
                    (this._scene.activeCamera.maxZ -
                        this._scene.activeCamera.minZ) /
                        2,
                    0.3,
                    false
                ).visibility = false
}

But still haven’t figured out how to load it from a blob url.

const skyboxMaterial = new BABYLON.CubeTexture.CreateFromPrefilteredData(
            url,
            scene,
            '.env'
)

This crashes the app when I use blob url.

well we will need a repro in the playground to help more :slight_smile:

if you don’t need a skybox, why creating it?

@Deltakosh I have tweaked it here to try and pull out what I am trying to achieve https://www.babylonjs-playground.com/#MT5AJY#1

I’ll have a look!

This is because the cubetexture constructor is a monster:

(I promise new classes are all using options instead of never ending list of parameters :))
