Thank you for the suggestion, Gents!
I will do a search as suggested.

I have restarted Poser a several times since my first attempt with this. Also uninstalled
the old Apartment, did a fresh download, installed it and... the same issue!

But.. I solved it by getting rid of the images used for specular and bump.
Instead I used the image map (texture) as a bump. Works just great.

Regarding the lightset Dusk by Dawn, yep that´s the reason why I like it.
Same goes for the Office and Interior ligtsets. Recommend them.

Thank you

Quote - Oh, and if that IBL is a sky and rocks, I have to really ask WHY? Why are you lighting an apartment interior using data from an outdoor sky/ground IBL?

**Trial and error ?

**The Future Apartment is one big prop without the ability to make walls invisible
, none of the lightsets I usually work with is usable with this product, but I have
decided that ,because I like the style of it, I will make it!
Anyway...

Always happy for constructive help!

Quote - Hmm. It's really hard for me to see what is in those images that are used in the wall shader. It looks like a photo or render of some machinery, although I can't exactly correlate the render in the first post with what I see in the wall material.

I know this has nothing to do with your problem, per se, but that material makes no sense to me whatsoever. Is that supposed to be a transparent wall and we see machinery behind it? Or is it supposed to be reflecting machinery in the room? Or is it supposed to be a painting of machinery on the wall?

-Beats me, but the wall is not transparent.

In any case, none of those would justify using a photo of the machinery as a bump map on the wall, which is what you've got there. 

If I were you, I'd remove all that crap and make the wall a flat color with no specular, unless you mean for the wall to be made of something shiny. This is an apartment, right?

-I will try that solution!

Meanwhile, if I understand you correctly, what we see on the wall is some sky and what looks like a stone. Is that right? And you say that is the image attached to an IBL? (You said IBL AO, but that makes no sense. AO is ambient occlusion and we don't connect an image to AO.)

So you're seeing the image in an image based light projected on your wall? Could it be you forgot to set the light type to IBL? Because if you have it set to some other type, such as infinite or spot, then an attached image is like a gel or slide in front of the light. In such cases, the light would behave like a slide projector, and whatever it shines on will show the image, just like using a projector.

-Well, I haven´t forgotten anything, the lightset I have used here (in this example) was    included in my Poser 7 copy.  As I mentioned before, same issue occurs whatever IBL lightset I use!

If I haven't guessed right, come back. If you do, could you show me the light material settings and properties + parameters of the light.

If there's any doubt about what lights are doing what and you have more than one, I'd do a render with one light at a time.

In future, don't ever bother showing me the "Simple" material version - that doesn't show what is really going on. The nodes show me the true setup.

-Hear you!

**Thank you for the fast respond :)
There is nothing in the scene but the SF Apartment prop, so there should not
be anything else to reflect!
I say reflect because the imageyou can see on the wall, is the same as the one
connected to the IBL AO.

No, if you look closely you will see his shadow on the ground.
