IR not synced with timeline when scrubbing

Corona Corona for Cinema 4D Issues
1

I’ve found some, what I think are transformation bugs:

New scene, just corona sky, create an object, rotate it P -90°
Animate H rotation from 0°to 360°over 90 frames.
Start IR and scrub the timeline. What you see in the viewport and what happens in IR should not match This only happens if I rotate P to -90°

This first happened when I was importing a new object and it was not rotated right, so I corrected it to P -90° and keyframed the H rotation. Here’s a short screengrab:

I’ve also uploaded a scene file.

I was able to reproduce this on Cinema R18, R19, R20 with Corona 4 and Corona 4(hotfix 1) on 2 different workstations using Window 10.

Hi Matej,

Thanks for letting us know. Unfortunately, I’m unable to reproduce this with your scene file or by creating a new scene. Regardless, we will look into it.

Just a note:
Am not sure, but I think it’s a bug in Cinema.
Cuz similar thing happened to me while testing RPR. And along mirroring issue, after couple of RPR restarts, I also got full Cinema freeze. Wasn’t even able to kill the process via task manager, but had to restart OS.

Hi Ben,

I also tried to recreate this in RedShift, U-Render and ProRender it works fine. Corona interactive is the only one giving faulty feedback, so it might be Corona after all.
Those others are GPU renderers, so not a fair test, really. The only thing I can think of is that I’m using dual CPUs in both workstations. Maybe you’re using a single socket?
W1: 2x E2670, 64GB DDR3
W2: 2x E2695 v4, 256 DDR4

@burnin
I don’t know, since I don’t have any CPU interactive renderers. Maybe arnold

Hi Matej,

Is this still happening to you? :smiley:

Yes. Just tried with the latest daily :smiley:

This is so odd. It works perfectly here for me :frowning: Can we have this test scene? :smiley:

Scrubbing the timeline with the IR doesn’t work for me either, at least in the latest daily v5 :frowning:
