Camera type - Request

[remKa]

Hello,

Could we have the possibility to switch between Universal or Realistic Camera inside the camera parameters ?

And would it be possible to add a "reset to default value" for each parameters ?

There are these possibilites in the Houdini plugin and this is pretty handy

I agree would be nice to switch between the universal vs realistic

I did create a macro script a while back that lets you create a Universal camera or a Realistic camera from the current active 3ds Max viewport view. I would always use the create camera from view in 3dsmax for Vray Cams or Physical cameras but no option for doing that with Octane cameras

You can configure some of the defaults in the script. I suggest either updating or removing the ocioDisplayName to your display view or remove if you do not use one

Install
- Just drag the macro into Max,
- Restart max
- Customise toolbar > Quads/Toolbars > Category 'Byrom' > Create Octane Camera from view


works with latest version of Octane Plugin 26.5

I have a lot of trouble using Universal Camera and Realistic Camera, a lot of focus bug, unwanted depth of field... anyone has the same issues ?

In my script

cam.FocusType = 0

This is the 'Focal Depth' focus type, and you need to change the focal depth in meters or use the focus picker in the render view to get the correct focus.

If you want autofocus for example, then change the script so the values are

cam.FocusType = 1

For the Realistic Camera, they have a fixed aperature meaning you will always get depth of field, which could be perceived as out of focus if your focal type/depth is not set correctly

However, for the Universal Camera I set

cam.aperature = 0

Which disables DOF completely for the Universal One and will speed up the render.

One other thing. If you have a fog volume and try to use the focus picker in the OCtane render view it will not work correctly and will focus fog 1cm in front, you need to hide the fog, pick focus and re-enable the fog

Thanks Tombyron but I'm using too many scripts already :p

But I really need the dev to correct the bugs !

(btw I wish I had your scirpting skills ^^)

[tombyrom]

Thats fair enough Remka! No worries

But to answer your earlier question, I dont think I've ran into any specific issues, but certain setting combinations can look like issues. To be honest I mainly use the standard viewport camera (or even Physical cameras) day to day. Octane camera take a bit more work to setup which I agree could be improved

Hi remKa,
The Realistic Camera is meant to simulate a real-world camera. It uses specific lenses, each with its own inherent characteristics, and everything behaves according to the logic of the selected lens.
Because of that, you can’t expect a one-to-one match when switching from a Universal Camera to a Realistic Camera. Going the other way might get you closer, but there will always be some limitations. Just my two cents. That said, what issues are you seeing with the Realistic Camera that aren’t related to these expected limitations?

Hello Paride,

the main purpose of this topic was the request to have the possibility to switch between camera types inside the camera modifier, not for a perfect match between them, I'm aware of the strengh or limitations of the three types, but for quickly test different settings : for some shots I need a nice chromatic abberation and on some shots I need a standard octane camera for more flexibility.

I found it pretty convinient to have this choice inside Houdini ^^
