Quote - I did what bagginsbill said. I made 4 Pictures and my boyfriend was holding 4 different sheets of paper with the following german words: vorne, rechts, hinten, links (front, right, back, left).

I made a panorama out of it and attached it to the sphere without changing the U Scale.
After rendering it I was not able to read the words. Vorne (front) looks like enrov (tnorf). That is wrong. A V4 in my scene would have to read a word from back to front :blink:

Then I changed U Scale to -1 and now it is correct. It looks like vorne (front).

bagginsbill, did I get the problem?

Exactly. It is perfectly clear which way is the right way, no?

Now that you have oriented your words correctly, then tell me in what order should the words be in your picture?

North->East->South->West

or

North->West->South->East

Cath has been insisting that west follows north because she refuses to reverse her picture. If you accept that the picture MUST be reversed, then it follows that the order of the compass points is NESW, just as in real life, because now the picture is homologous to the actual world around the camera.

I don't have much time to post today, so just a quick note.

Some of you think I have been offensive. 

First you should realize that Cath jumped into a couple other threads and continued to assert that I am confused. I have asked her nicely over and over to do specific tests. Instead she does her own results that continue to confuse and prove nothing. We brought it back here because I said this is the place we should be discussing it. It looks like I snapped at her, but only because you didn't see the other 20 postings that preceded those throughout the day.

Second, everybody should stop worrying about who is experienced, who is kind, who is nasty, and who is pompous, and just do the experiment yourself and show your results. If you think I am pompous and insulting, let me remind you again:

I was not going to even come here. I was asked to participate because I have a lot of knowledge to share on the subject. I also have technology to share, but I'm not sharing it yet because there is so much confusion caused by one person. Cath started this whole thing by saying, with regard to an older thread by me on panoramic images and matching IBL:

1. I was confused about East and West
2. The Poser sphere was perfectly UV mapped and I was confused about that too
3. You have to use a 2:1 image
4. My lighting was dull.

Quote - I read this some of the things there are not really correct.. and the effect of the renders are washed out and not match that well the backgrounds.. as it should be especialy with the sphere map with the west east direction are not correct.. sphere in poser is mapped correct he just use wrong proportion, all lati/longi need the be 2:1 and not 1:1 ..but fine i did the same mistake with poser6 and ibl but that was 2 years ago ;) today we got smarter! lol

I then proceeded to demonstrate that 

1. my compass matches my rendered diagram and my rendered images. 
2. the sphere is not UV mapped on the west side correctly
3. you can use any size image
4. My lighting is not dull. That was Poser 6. When I render with Poser 7, the lighting is respecting HDR. I didn't really talk about this point, but it was really insulting that she slammed my Poser 6 lighting. Poser 6 refuses to do bright lights in IBL. It has a clamp internally. Poser 7 looks different, not just because of HDR images, but because the Poser 7 math is different. We've gotten so confused since then, I have not even had a chance to talk about this and show you why it matters, even for LDR images.

So now it turns out, after a LOT of arguing, that I was entirely correct about the Poser sphere. In fact, I have reported the sphere and seven other props with bad UV mapping to eF, and it is now an open bug which is being corrected for the next release. We got a new sphere to use from Cath, which I consider to be very helpful of her. I would have thought an apology was in order after all the trouble she caused about this, but I don't really need that. The sphere is nice. But you still have to U_Scale = -1 it to make it work right. I made a better sphere already, but I didn't want to insult her. She should have reversed the normals so you can see the image in preview, and she should have done the U coordinates in the opposite direction so that the orientation is correct and you don't need the U_Scale = -1 any more.

I assure you, I have been corrected about many things here at Rendo. When corrected, I have acknowledged my mistake and then exploited the new knowledge with happiness. I do not worry about my reputation. I could care less what you think of me. I do worry about facts. And I do get annoyed when I take extreme measures to test my hypotheses, demonstrate experiments that support my hypotheses so you can reproduce them, and also demonstrate experiments that contradict other hypotheses. In other words, I care about clear, logical thinking. This thread is loaded with illogic (not just from Cath) and so you hear from me a lot. I'm sorry for those of you who find scientific discussion intimidating. But you have no right to take issue with the things I've posted. They are all on-point, and reproducible by you. And I didn't start this argument, but I will finish it.

When I'm absolutely certain that I'm right and I can prove it, then I really don't care how much experience you have, or what work you've done, or that you think I'm arrogant. I really just care about the facts, and anybody who argues a false argument over and over is going to see me come back again and again with new things to try, new things to see. But Cath refuses to try my suggestions. Do you think I'm badgering her? I'm not. I'm stating the facts over and over. I have proven my case with dozens of renders. 

Cath needs to stop pounding her chest about her years of experience. I don't care if you're the president of France, or the Pope, or my high school physics teacher. If you're going to argue with me, you have to prove your assertions. Here is a certainty - one of is right and one of us is wrong. I have proved my assertions - there is no inconsistency that anyone can actually prove in my work with photographs mapped on a sphere viewed from the inside. Cath has not yet done a render from inside, so we have no evidence one way or another that words appear backward to her if she does it her way.

Dorelia has demonstrated who is right. Can you?

Which of my actual renders has East and West mixed up? Can anybody point to one? So far, no. So why am I the bad guy? Cath started all this by telling everyone that I am confused, that I do not understand the coordinates, that it is ok, we can forgive the poor noob, he's still learning.

You don't find that insulting? Even if I was wrong that is pretty insulting. Now maybe some of you still don't think I'm right. And it is because you think I'm wrong that I am also even more wrong for continuing to "cat fight" with Cath.

Keep holding that thought in your mind. You think I am wrong to argue so much, because you think I'm wrong about the U_Scale = -1 and the NESW order,  because you agree with Cath and not me. And so it is OK in your mind that Cath told you I was was confused and I will learn the truth when I'm as experienced as her, right?

But think carefully about taking that position. Because the reality is if it turns out that I am not wrong, but instead I am right and Cath has been wrong all along (remember, she was wrong about the sphere's UV mapping) then the situation will be reversed and you will have to become angry at Cath for arguing so much when she was wrong.

Think about it. Do you really want to be angry with me? Do you really know who is right? Really? Like you'd bet your life on it? 

Do the experiment. Show your results. Which way should you turn to move from facing North to East? When you see compass signs in your virtual world should they be reversed or forward?

Do not talk to me about lighting. The lighting matches if you flip the U as well.

Remember I'm talking about Panoramic photographs, not hand-made diagrams.

By the way a photograph of a mirror ball photo does NOT need to be flipped. Because it is a mirror - it already flipped the world. Get it?

But a panoramic photo converted into angular map in HDRSHOP is indeed backwards and must be flipped for both the sphere and the IBL. If you do not, you have reversed the world. But we're getting ahead of ourselves again. Just show me your renders from inside your sphere, with words please in the photo, and the compass  inside - or something like it. The order is N->E->S->W if I am right. Cath says it is N->W->S->E - and it is FOR HER because her diagram is backward. Don't use a diagram - use people holding signs.Arrange the people according to how the compass points really lay out. As you are standing in the room there will be no confusion. Then make your render look just like how you know your room is.
