I’m trying to make translucent curtain material, but I keep on having an issue: If I view the material “head-on”, it’s very translucent (say, 30%), but if I change the viewing angle, at about 50 degrees, the opacity suddenly changes to about 90%. So when you walk around in the level the appearance of the material changes very drasticly depending on what angle you have towards it:
I figure there is some connection with the Basic Lighting Questions in my other post: Switching off the Mobile Directional Light makes the issue go away. However, I’m unsure how sunlight could affect this surface: there are many other surfaces in between that should be blocking the sun.
