Issue 7851
Object ID colors are not consistent between renders of the same scene
When resuming a render that previously crashed, or when doing a touchup render, ObjectID colors are different.
Object ID is used for masking in video applications and needs to have the same colors for the duration of the clip.
To recreate:
Create a scene with several objects and save the scene.
in iRay settings Enable ObjectID Channel
Select Render Scene
Select iRay Render (Image Sequence)
Render a few frames of an image sequence
Abort the render, or force quit the application to simulate a crash.
Resume the render from where it left off, or replace one of the rendered frames.
Observe the new Object ID colors are different to the original render.
Expectation:
Object ID colors are the same between renders,
Attached:
2 Object ID frames where colors have changed after resuming a render.
