Hi,
finally I finished my shader. all bugs and crashes are fixed as far as I know. when implemting my shader into final project i noticed major malfunction.
When rendering in model window means "top,left,right,bottom,perpsective ...." by pressing ctrl+r everything works fine.
When rendering to image or movie by clicking the central render button or pressing shift+r all surfaces turn gray like not having any material assigned.
It seems my shader just works in model window. 
Question: How to get it work in final rendering process?

Greetings
Jimbo
