Corona and batch cam render plugin_sending to Backburner

[mitviz]

Hi guys, i have some scenes i setup to render with batch cam plugin and sent to BB but seems the beauty passes are coming out very black and the other passes seem ok, has anyone used this plugin with corona before? i should also state that when it does render via bb it renders just fine but when i check the saved files its where the issue is, the beauty passes are black
