Well as some people still seem to struggle with mirror, here is a mirror shader preset you can use with some primitive props.
- you must use 3Delight (software render in menu Render > Render Options)
- maximum raytrace depth should be at least 1 (in advanced render option tab)
- you have to render your scene (isn't it obvious
- It uses default DAZ surface shaders.
Keep in mind that the mirror reflects all things which are around. So there is nothing, or that that it is not enlighted (with 0 ambience), it will look black.
