How to make a dynamic cubemap ? (reflexion project)

Help & Support

Hi, could You make some example of dynamic cubemap that can be used as a skybox?
Im trying to do with Your hints but I still get an errors like: “Can’t use prefiltered cubemap: undefined, false, …” It seams like var allMips is not defined couse of the condition:
var allMips = prefilteredCubeMap128 && prefilteredCubeMap64 && prefilteredCubeMap32 && prefilteredCubeMap16 && prefilteredCubeMap8 && prefilteredCubeMap4;

var angles = [
                [ 0, 90, 180 ],
                [ 0, -90, 180 ],
                [ 90, 0, 0 ],
                [ -90, 0, 0 ],
                [ 0, 180, 180 ],
                [ 0, 0, 180 ]
            ];
    
    
    this.colorBuffer = new pc.Texture(this.app.graphicsDevice, {
        cubemap: true,
        rgbm: true,
        fixCubemapSeams: true,
        format: pc.PIXELFORMAT_R8_G8_B8_A8,
        width: 128,
        height: 128
    });
    this.colorBuffer.minFilter = pc.FILTER_LINEAR_MIPMAP_LINEAR;
    this.colorBuffer.magFilter = pc.FILTER_LINEAR;
    
    for (var i = 0; i < 6; i++) {
        var renderTarget = new pc.RenderTarget(this.app.graphicsDevice, this.colorBuffer, {
            depth: true,
            face: i
        });
        var e = new pc.Entity();
        e.addComponent('camera', {
            clearColor: new pc.Color(1, 1, 1),
            aspectRatio: 1,
            fov: 90
        });
        e.camera.renderTarget = renderTarget;
        this.entity.addChild(e);
        e.setLocalEulerAngles(angles[i][0], angles[i][1], angles[i][2]);
    }
    var options = {
        device: this.app.graphicsDevice,
        sourceCubemap: this.colorBuffer,
        method: 1,
        samples: 4096,
        cpuSync: true,
        filteredFixed: [],
        singleFilteredFixed: true,
    };
    pc.prefilterCubemap(options);
    this.app.scene.setSkybox(options.filteredFixed);

I really need this working for my project. Please help.
