Thank you! I will check every step! This is the HDRI that I am using: https://polyhaven.com/a/sunset_jhbcentral
As you can see, also in the attached screenshot, it is quite difficult to understand if the height of the camera was 1.8 m or 2m for example.
And I have other 2 questios. I didn't find solution yet on this forum. (Do I have to create a new thread?)
1) Is it possibile to link and hdri image to a camera so that when you rotate the camera the environment follows?
2) If i change camera's focal lenght the hdri changes automatically. Is there a way to detach this connection? That would be stupid? Thank you!
1.8m or 2m - with a value range so narrow it will probably be impossible to tell without knowing some dimensions in the HDRI, for example the distance between the tile borders or those cylindrical whatever-they-are. Also, I'm not sure the roof in that HDRI is level, if it isn't this introduces another level of uncertainty.
1. I guess it should be possible with parameter wiring, where you'd wire the HDRI's U offset to camera Z rotation. But I'm not sure this will help as parameter wiring in Max tends to be slow and with the texture being recalculated whenever you rotate/change the camera it might be too slow to work interactively.
2. Yes, this is correct and expected. If you think about it, changing the FOV should of course show less of more of the world surrounding you. I don't think you can expect this to work independently without creating other problems - for example you could change the scaling of the U/V parameters of the HDRI but this will cause problems where the HDRI wraps around, the seams wouldn't match anymore. Plus, you're likely to see that something's not right.
