Lights not working in VW2020 in Troubleshooting Posted November 21 On 11/5/2020 at 2:58 PM, P Retondo said: Thanks, klinzey, I will check out those situations. Regardless of that, this is a user interface problem that VW needs to rectify. There should be one and one place only to set the visibility and shadow-casting properties of a light source for ALL rendering modes, and other toggles that affect this behavior should be removed. I had not noticed these changes up through vw2017, but since I started using vw2020 all of a sudden my former methods for lighting are not working. I would tend to disagree with this. It is crucial to be able to have the potential to cast shadows or not per texture. If you place a light object inside a piece of geometry, the texture applied to that geometry needs to not cast shadows in order for your light to work. Not casting shadows is often helpful when using process renders when you want to investigate how things look without waiting for shadows to render.
