Thank you Richard. I did, but nothing happen. I been using environment Texture button 100 times with cycle without any problem. So Why it dont work this time.
When i Change over to Blender Engine there is no environment texture. I try 5 times. Still no work Sorry. I have already cyclematerials.
Sorry this dont work. I never use nodes to add one environment images before, and always easy to add one and never had any problem before.
I deleted Blender from my imac and downloaded a brand new Blender from Blender Webbsite, but I still have problem to find button for Environment texture and then add images.
This is the latest downloaded Blender. http://www.pasteall.org/blend/42094
Thanks guys for helping. My new material settings with nodes work perfect.
Thank you. But I am not sure if World- Environment image button vill show up on my next blenderproject. (Without nodes) I still rendering so I can not find out right now. I have never use nodes before when i use World-environment button.
