Cam Keyframing While IPR Active Tweet

[peteg]

I'm running into an issue with camera keyframe animations when the IPR (Qt5) is active.

a. Windows 11 21H2 (22000.708 OS Build), b. Nvidia 3090, c. 128 GB, d. 512.96 (Studio), e. Not Installed, f. 2021.1.5.0, g. Houdini 19.0.622

Steps to reproduce -
1. Have a camera with keyframes set (test scene file - https://www.dropbox.com/s/a00yiogqqsq05 ... hiplc?dl=0)
2. Activate Octane IPR (Qt5)
3. Go to an existing keyframe and move the camera by navigating in the viewport (changing values in the parameter dialog doesn't cause this issue)
4. The camera no longer animates between the keyframes, but the keyframes retain their values
5. If you disable the IPR and then change a value at either keyframe, the camera animation works again

Thanks,
Peter

Hmm, what a weird issue! It also affects the Houdini viewport even after closing the IPR window! Really I can't even figure out how this can be possible, but I'll investigate it.

I can verify that the same happens with Lights.
If I create a Spectron Spotlight and tweak its Throw distance and Cone Width values IPR acts properly.
If I keyframe these and then try to tweak them, the IPR does not reflect the changes.
Deleting the channel and now we can tweak them again in real time.
