I started to write this shader because I was trying to render with light probe HDR images in XSI but can not find a proper mapping methode. This is a taste with a light probe HDR image and f3DEnvBall shader. |

Simply a NURBS sphere with displacement map which was illuminated (using final gathering) and traced reflection by the backdrop environment shader with the HDR image. |
