Cath stop talking about lights. I already told you I'm not going to discuss the lighting. Every time I try to pin you down, you talk about lights.

But we already established that if you flip the panorama and flip the angular map - they still match. Stop talking about lighting consistency. That is not the point. The point is that you keep finding excuses as to why you cannot show me something with WORDS in it in your render that is correct. Any photograph with a sign in it will make it clear. You say do not use panoramic pictures that are "merge God know which direction". Why is that a problem. Are you unfamiliar with the New York skyline? Do you know the Statue of Liberty? Which arm does she hold up - her right arm or her left arm. Everybody knows it which is which. Put a picture of the statue of liberty on your sphere with U_Scale positive. Render from inside. Show yourself that IT IS BACKWARD. Now use U_Scale negative. Render from inside. Show yourself that IT IS FORWARD. 

Use words - signs - logos - office buildings, store fronts, whatever. This is not difficult, yet you have refused to do it for us even once.

You CANNOT use a photograph with U_Scale = 1 from inside the sphere. It is backwards. You can refuse all day, yet it is most definately backwards. It will only show forwards if U_Scale = -1 or some other negative number. And therefore, so to, must the IBL be flipped to match.

Don't say any more - prove your words. Not with a diagram, with a photograph. Do not draw North West South East. Do not draw North East South West. Show us a photograph, either one that has words in it, or one that is famous and asymmetrical. Do not show us, for example, the Louvre - who can tell left from right there? Too bad because I myself made a panorama in the Touilleries of Paris. Unless you know the garden pefrectly, nobody would know reverse from forward. In fact I have quite a few panoramic photos I took myself, but no words in them. So I can't prove it with something I made.

Hmmm. perhaps I can make a new one.

But now my dear friend, I'm going out to dinner and drinks and I'm going to make a toast to you and hope that by tomorrow we all know which way is East and how to use a photo as an environment sphere. Then I can give you new goodies.
