Replicator - Camera not rotating (in 2022.1.1)

[peter.gaston]

btw, this works in 2022.1.0

The commands in the yaml file…

# camera
camera_coord: (0, 0, Uniform(.20, 1))
camera_rot: (Normal(0, 1), 0, Uniform(0, 360))

Do not appear to work. I would expect the camera to, at minimum be rotated randomly in a circle - the last “Uniform(0,360)”

This comes from the given file parameters/warehouse.yaml - running it nicely moves objects - but the camera doesn’t move/rotate.

Here are three images from running the tutorial script. Note the background doesn’t move.

Hi @peter.gaston , this is expected behavior. The camera’s position is not randomized for every frames. It is randomized only once in the scene. This is a limitation for the old syntax of the composer, because sometimes we want to randomize for every frame, sometimes we want to only randomize at the beginning, and this applies to any prims in the scene. We have a plane to develop a new syntax that will solve this issue.

@jiehanw any news?
I need to use this parameter, do you think we should get an update soon?

kind regards,

Hi @stefanino . Yes, we currently have a complete new syntax that you can refer to. We called it replicator_yaml. You can refer to here: Replicator YAML — Omniverse Extensions latest documentation
To change camera’s position for every frame, you can do

trigger:
   trigger.on_frame:
      max_execs: 10

with.trigger:
  with.camera:
    modify.pose:
      position: [10, 0, 0]

awesome!
