Setup:
- Create object
Animate it moving or spinning fast
Select object
Octane > Octane Properties > Movable proxy
Render settings > Enable motion blur
Bug:
[list=]When using the octane viewport and scrubbing the timeline everything looks OK
When rendering single frames from any point in the timeline everything looks OK
When rendering a range of frames (active time segment or range) the first frame looks OK but every subsequent frame the object is cropped in the direction of travel, as if the motion blur alpha channel is binary and the smooth transition from solid object to background is simply cut out. Even if you change the range from 0-100 to 1-100 the first frame (#1) which was bugged in the previous render is now fine and the first bugged frame is #2[/list]
It's something about rendering them back-to-back that causes it
If I save the scene, revert to version 3.08.2 - 5.12, and re-open the same scene. Everything is fine.
