​Problem summary
If a key-framed stereoscopic camera is rendered first in the Timeline, then any non-stereoscopic cameras that are key-framed after the first camera, render two images from left and right as if they were stereoscopic cameras.

 

Customer reported version
Modo 12.2v1 

 

Customer reported platform
MacOSX 10.14

 

Steps to reproduce

1) Open Modo and create a sphere. 


2) Create two cameras. Name the first camera "Stereoscopic" and the second camera "Mono". 


3) Select the "Stereoscopic" camera and open its Properties. Enable the "Stereoscopic" option in the Camera Effects tab and change the "Stereo Composite" option to "Side-By-Side".
 


4) Switch to the Render tab and select the "Render Item" from the Shader Tree. 

 

5) Select the "Stereoscopic" camera as the "Render Camera" in the Render Item Properties. Keyframe the camera selection on frame 1 in the Timeline. 

 

6) Change the "Render Camera" selection to the "Mono" camera and keyframe the camera selection on frame 2 in the Timeline. 

 

7) Move to frame 1 in the Timeline and start to render the scene with the "Stereoscopic" camera. 

 

8) Move to frame 2 in the Timeline and start to render with the "Mono" camera. There are now two images rendered from left and right and this is not correct for the "Mono" camera that is non-stereoscopic. 

 

 

Workaround
Disable the "Stereoscopic" option in the Properties of the stereoscopic camera before rendering with non-stereoscopic cameras that are key-framed in the Timeline.
