Welcome interested in this question. Do you recommend to create a curved Plain outside the window as a background. I met another option - not a ragged Plain, arc, or something like that, and it is a closed ring envelope over the entire circumference of the stage. It is clear that such a ring it is necessary to appoint a panoramic map. I would like to know whether this panorama card to perform on their own? That is, we all know that the customer likes to look at the design of the project as close as possible to reality, and therefore he likes to see the real picture of the yard areas, roads, environment. How to make a panoramic photo?

Hello! Of course you can. Just take a picture of the back you need. Do it thawing horizontally and assign to ring and tile the required number of times in the parameters of the material so that it is not stretched.

As for panoramic photography, the real terrain, it's more likely that you will not get a real panorama from the geometric center of the building that you will render. Just because you can not tear down the walls of the building to put the camera in its center😁

In general, when talking about backing behind a window on the renderer, this is a slightly incorrect approach. I would say a very commonplace. We just need to understand that backing behind the window in 3d is necessary, only in one single case - "blood from the nose", "on the vase" in the scene "the trees that are seen" should be reflected "outside the window. That is, when it is necessary for a particular back to be reflected on the objects of the scene.
However, such a need is farfetched, rather than really relevant. In this connection, the easiest way is to do alpha on the windows and at the post-processing stage simply insert the necessary backhand there manually. This is incomparably simpler than fiddling with adjusting the angle, position, brightness, etc., for backing up on an object outside the window or nested in the Environment.

Much more literacy to think in advance what kind of views will be visible on the render, go to the object, stick the fotik out of the window and make flat pictures of the necessary views of the surrounding environment.

If we are talking about an exterior renderer, then we will go back to the point of shooting, which you will not be available once, except if the object is not yet built. But again, on a photo instead of a design landscape with trimmed flower beds, as always there will be piles of bricks, concrete mixers and construction debris😁

It is just necessary to revise the concept in general, like a real HDR panorama for a building object.

Of course, you can take a professional fotik and click on the photos on the panorama. Then sit and stitch it in the panorama prog, then go through the quests with the back setting in the scene, etc. But is it worth a minute's whim of the customer? More precisely not so, whether he is ready to pay for it accordingly? 😁
As for the actual process of creating HDR panoramas, the network has many lessons on this topic, if you are interested in them, then look for them on the forums of photographers and photoshoppers, the benefit of such a lot. The description of the technique of HDR photography and panoramic photography, it seems to me, slightly goes beyond the 3d theme 🙂

But if you still decide to do it, then we can continue it here.

Hello, I need help! The problem is that I do not have the correct imposition of HDRI maps on the scene lighting. I use HDRI map for the lighting using a light source such as vrayLight Dome stage, type of overlay maps - spherical. But to render clearly visible jamb overlay maps. Actually the image itself to the jamb:

Hello! Cant what? The fact that the image on beke rotated? Go into the setup HDRI maps and simply rotate it as needed😉

About the turn card, I know she scaled! Is it possible to reduce the scale?

Yes, you might say tiling when talking about a specific angle.

If we talk about all invayroment , you chose a failed card, as it certainly appears correctly, that is what this is.

Take home instead Lite do hemisphere luminous and pull at it this map or jpg analog, and see that it is applied exactly as it should be superimposed on this map of the hemisphere.

If yes, it is! Thank you in advance.

Why, when you put back the HDRI, everything above the horizon in the alpha is filled with white? With this you can somehow fight?
