Hello.

It seems in the last update we have some camera controls broken.  
I’m using Vray 5.2 update on Houdini 19.0.455.  
All related to lens shift and offset has no effect when adjusted.

As I am in the process of migrating from 3dsmax to houdini working in the archviz industry I find this as a big problem. Could we get a fix any time soon?

thanks!!

Seems to work for me. Could you please send me your .hip file?

Well, you’re right about Auto. Vertical Lens shift but I was hoping to have feedback in the viewport.  
Vertical and Horizontal Lens Shift seem to have the same behaviour, are seen only in render but Horizontal and Vertical Offset are definitely broken. They don’t have any effect in viewport and render.

As I can see changing the expression of the offsets from: -ch(“./winy”) to ch(“winy”) fix the problem but you should change it by default.

Any way to have a viewport representation of the Lens Shifts?

Thanks!!

I’m not sure any changes are required, our QAs will check this…

No.
