Can't Launch project after 2 month/ worldLayer.instances is undefined

Help & Support
1

Hello,
I have a problem with an experience that we created some time ago. I tried to launch the project out of the editor and now it shows this error:

worldLayer.instances is undefined

RenderPass cannot be started while inside another render pass.

[outline-post-process.js?id=99952366&branchId=1eeb734b-1ed2-4c90-8bb8-4d1fae7262ba:348]: TypeError: worldLayer.instances is undefined

Experience loaded fine last time I used it 3-4 month ago…
Maybe some can point me in the right direction?
Thanks!

Your references code uses private functions, which changed. Something like this might work:

before

    for (let mesh of worldLayer.instances.opaqueMeshInstances) {
        if (mesh.originalMaterial == undefined) {
            mesh.originalMaterial = mesh.material;
        }
        if (bool) {
            mesh.material = this.getNormalMaterial();
        } else {    
            mesh.material = mesh.originalMaterial;
        }
    }

now

    for (let mesh of worldLayer.meshInstances) {
        if (mesh.originalMaterial && mesh.originalMaterial.transparent)
              continue;
        if (mesh.originalMaterial == undefined) {
            mesh.originalMaterial = mesh.material;
        }
        if (bool) {
            mesh.material = this.getNormalMaterial();
        } else {    
            mesh.material = mesh.originalMaterial;
        }
    }
