i have one layer (layer A), and i want to apply advanced lightning to it, but as a separate layer (layer B) on top. I want the "alpha obstacle" to be checked,
but the layer B is not "recieving" the alpha information from layer A. I clicked on show alpha and indeed layer A's alpha is properly set, but layer B (new solid, with advanced lightning applied) is simply ignoring the alpha from layer A.
How can i get layer B to "have the alpha" from layer A? Or what is the correct approach to having advanced lightning on a separate layer?
