    Hi,

    We tried switch to 5.6b9 and 5.6b10 and we see this error:

    Enabling or adding a Renderer during rendering; this is not allowed. Renderer 'New Game Object' will not be added.

    if fact, we use SetActive(true) inside of OnWillRenderObject()

    but under 5.5.1f there is no errors.

    What changed?

    I'm seeing the same error with 5.6.0f1. I didn't see this in 5.6b11 or 5.6b9.

    Hi,

    I think this is a side-effect of some graphics bug fixes. The behaviour now is:

    Prevent adding/removing renderer from inside OnPreRender() and OnWillRenderObject() callbacks.

    This is because the output from the scene culling has been determined (at this point in the rendering pipeline) and changes to the scene could lead to the culling output being out of sync with the scene which can lead to rendering bugs and potentially crashes.

    Thanks

    Jake
