Glass shader renders incorrectly unless renderer component is disabled and re-enabled

[Gmod4phun]

Describe the bug

Some models don't render correctly until the renderer component is disabled and re-enabled after setting the model. Changing the model to something else and then to the one you want does not seem to fix it either, only reenabling the component does. In this case its a model with the glass shader, where the reflections dont work unless said steps are done.

Once the model was correctly rendered, switching to another model and then back to previous one renders it correctly. However, after clearing the model to the empty default, and then selecting the new model again, it will render incorrectly until the component is re-enabled.

To Reproduce

1. Add a ModelRenderer component to a GameObject
2. Pick a model that uses glass shader
3. See broken reflections until you re-enable the component

Expected behavior

All models should render correctly without the need to disable and enable the model renderer component.

After some more testing,I think it has something to do with the SceneObject flags not being set properly.
