[2021.12380/CameraCOMP] Position?

Bugs
1

I updated Build 2020.25380 to 2021.12380.
(windows10)

After that, the roateting angle is changed by “Position” value in [CameraCOMP] that I’ve used “Look At” and “Path SOP”.
For example, before the facing front on Geometry was by 0.25 position value. But now it’s 0.75.
The same phenomenon happens on my two different windows PCs.
Is it caused by the new parameter “ForwardDirection”?
Or it’s my particluar case?

Thanks.

Sorry for the late reply on this. I think it is actually the Circle SOP that was changed that is affecting what you are seeing.

In the first 2021 release (see notes here: 2021.10330 | Derivative) there is a backwards compatibility warning that the direction of the circle was flipped because it had been inconsistent with our other SOPs.

Because of this flip, the camera will now follow the circle in the opposite direction to the way it used to go. You should be able to fix this by using a transform SOP to rotate the circle 180 degrees. If you want to see the order that the camera will travel around a path, you can turn on the ‘Point Numbers’ using the display options in the SOP viewer.

Sorry this caused problems for you. Let me know if you have any questions.

Thanks for your answer.

I understood the cause.
I will edit old files.

Thanks a lot!
