Same camera position in Maya and in UE4/5

cmdrDsig

Hey !

I'm currently trying to recreate a shot that I took irl, my goal is to compare the Arnorld renderer to Unreal Engine.
To do that I need the two final renders to be axactly the same when in comes to coordinates. Same camera angle, distance relative to origin, settings.
How would you go about doing something like that ? Is there a way to export cameras and import them in unreal ? 

Thanks !

Unreals default importer does some non-intuitive stuff with pivots. You probably want to check out the Import Into Level (FBX Scene Import) | Unreal Engine Documentation, as well as read about the "bake pivot to vertex" option. 

Basically, that allows you to import an fbx and it will maintain the same world position as in your DCC. 

I don't know anything about camera import specifics, but if there isn't a specific solution for that, you could put a locator or dummy geometry in the cameras position, import that, and then at least you have a position you can snap an unreal camera to. 

You may also want to be aware of unreals cinematic camera, versus the default camera. That allows you to change things like focal length, etc, the same way as you would in maya.

That's some very good advice ! Probably saved me some time searching for camera settings in UE
The dummy method will probably work too thanks a lot, I assume I'll just have to copy and paste the rotation values from one to the other so that they match.

There's a left/right handedness discrepancy between the two iirc. 

As Alex suggests you're likely best off transferring data via fbx - especially if it's animation

USD does also import cameras in Unreal.

Thanks to both of you for your input, I'm about to try this !
