Vray 5 cámara effects...about vertical lens shift

V-Ray V-Ray for SketchUp General

Hi Konstantin

I have been using vray for a long time, but i have never played with both vigneting and vertical lens shift.

since sketchup 2015 or sketchup 2016 can bring 2 point perspective, but i wonder when i dont have the 2 point perspective in sketchup and i want to do a render for a particular point of view how do you guess what it is enought.

Yesterday when i returned to my house just to relax i turned on sketchup 21 and vray 5 and play a bit with interactive render, i did an experiment didnt use the 2 point perspective of sketchup and begin using the vertical lens shift.

How do you use it???

How can i now that the value is the correct??

Does it make a really solid 2 point perspectiva???

Is only this value needed or we need the horizontal lens shift too for a great 2 point perspectiva?

I spent a lot of time triying with interactive render just to match a great 2 point perspectiva

First time in all my life that i touch this values with vray

I found usefull for a particular point of view but at the same time i spent a lot of time here, it was enjoyable time but a bit stressfull.

Is there any tricks here???

About vignetting is usufull in modern times??

Does modern cámaras still use vignetting???

It is an amazing journey with vray, i always find something to lern or to discover.

Thanks Konstantin
Best regards

Hi @luisgamino2 ​,

How can i now that the value is the correct?? The appropriate value depends on your specific scene. Currently, V-Ray does not offer an option to automatically estimate the correct value for the Vertical Lens Tilt.

Is only this value needed or we need the horizontal lens shift too for a great 2 point perspectiva?​ Yes, you can achieve a Two-Point Perspective by using the Vertical Lens Tilt.
Is there any tricks here??? There aren’t exactly any tricks, but as a faster alternative to Vertical Lens Tilt, you could use SketchUp’s built-in Two-Point Perspective option. However, note that this option does not offer any control over the perspective adjustment.
About vignetting is usufull in modern times??

Does modern cámaras still use vignetting???​Yes, vignetting remains relevant. Most lenses, especially wide-angle ones, exhibit vignetting effects, including modern lenses.
