Feature Request: Link Daz DoF to Octane DoF Parameters

Hello,

I would like to suggest linking the DAZ DoF control to octane. Currently it is very easy handling DoF with DAZ (especially with the F/Stop plane). These changes in Daz however do not translate to Octane. I understand that the same controls exist in Octane. However when making changes in Octane, these do not show on the DAZ Viewport.

So the current workaround is to make all changes with DAZ DoF and then copy the settings over to the Octane parameters.

So my request is simple: Can the DAZ DoF Settings be directly linked/copied/applied to the Octane DoF settings?

they were once linked, but it didn't work that well; the common sense back then was that the results are barely comparable, so the oc cam aperture should not be linked to the daz fstop.

apart from that in studio changing the fstop does also move the focal point, where octane will always focus to the exact point given by the distance, so this also translates not very well.

is from your experience using a fstop value from daz in octane giving similar/expected results in octane?

thanks for the great explanations!

Instead of just selecting 50mm F 1.4 the users will be able to select a specific lens from a preset menu (like SAL85F14Z ) that will then include all the information even with option to correct Chromatic aberration or keep it as produced by the actual lens.
that would be indeed great. from my pov it is also a logical step at some point. of course there is a lot of other homework to do until such features literally leap into view ;)

Those users who are familiar with photography will find that focal lenght, F stop, aperture will more or less behave as expected.
i was always keen to know if the f/stop translation works in mimicking real world f/stop values; the oc "thinlens" cam is based on a pinhole model, with only a variable aperture, so the f/stop value i implemented for the daz plugin is just an approximation (i am used to think in f/stop numbers, so the -reverse- aperture value was always a tad to synthetic for my taste).

A quick workaround is to quickly switch those object invisible in the DAZ scene tab, adjust focus and done.
what is on my rather long list of "nice to have" is

- an additional focus mode that combines node selection and the surfaces focus distance which i get from the viewport click (in other words a "see through" focus)

- additional abilities to set a focus area instead of only a focus point, or even multiple focus points, and to also freely move the focus point/area within the view (just like real cam autofocus controls)...
