WebApr 12, 2024 · 1 Answer. If you look at reference photos online, it does appear that glass casts a shadow of sorts. What happens is that some areas are darker and some are lighter due to refraction and reflection. In blender, it looks like the default settings don't allow the full amount of light through, so I ran a series of tests. WebNov 9, 2024 · Problem 1: Large light sources vs. small light sources. But in doing this, we start to discover some limitations. As the rays leave the camera in search of light sources, if those sources are large in scale — such as an environment light or large area light — they can be found very easily. on edge millies story
