- Now that we've got a flashing red light,…let's get some interactive lighting on the mantis.…What we want to do is have red kicks…on the mantis in sync with the animation…of our red light.…To set it up, let's turn off a few things…that we don't need, such as the gravity waves…and all of this stuff here, so we just have…the mantis and the background.…So we'll put it in right here, this is our mantis layer.…We don't have separate lighting passes…like a spec pass that we could use to put…specular kicks on it, so we'll do the next best thing…and pull a luma key on the bright spots of the armor,…and then only kick that with the red light.…
