You mention to make the image white. Does that mean delete the layer I used the brush tool on to add lighting along the edge adn make the entire thing solid white background? Leaving the Alpha texture I placed in step 5?
Hi Lorne, yes, that's correct.
Is my image showing up yellow because I have RGB set in PS? Should I use greyscale?
No, RGB is fine. The reason it has a yellow/green hue is that the Glass
material will still reflect the surroundings a bit. By default, the Reflection Control object which is used to generate the 360 degree reflection texture that is projected onto all reflective materials is placed high above the terrain.
So what you're seeing is in fact the terrain outside your building, being reflected on our glass ceiling/cove lighting plane.
What you can do is to add the Reflection Control
object to the middle of the room (Lights & Special Objects category -> Utilities
), so that it will generate the 360 degree reflection texture based on the surroundings inside your building.
Just bear in mind that the result will never be perfect as it's nothing but a simple workaround. In my sample scene, the cove lighting texture looks weird right above the camera for example, so the illusion is broken the moment you look up. In other words, your mileage may vary
