I'm trying to render an interior-lit column of milky, light diffusing plastic, and I can't seem to get the light distribution to be more complex; i.e. it just looks like I applied a light material to the exterior of the column, or like a glass tube with a beam of light suspended in it. I've tried IOR, translucency, refraction glossiness settings to no effect. The image below is what I'm getting with settings I would think would at least approach what I want, also below. Couldn't find anything on vraymaterials.de, either. I know I'm going to bruise my forehead with my palm once I figure this out. Thanks in advance!
