Heyas and welcome to Vue! :)

1. The "Unable to find light", just ignore it, I get it too, think it's from IBL lighitng from Poser?? doens't matter, just ignore it

2. Vue always starts with a Sun light. If doing indoor renders with no windows, delete it.
   However, I assume you are using the Sun, so you can adjust it by hand, or by precise controls (but the precise controls are only really useful when wanting to replicate real life,IMHO, such as light at 8am etc)

I will make you a new tutorial, give me an hour please :)
