Face Me Artifacts During Animations
-
Yes, I can reproduce it (see attached).
Now I understand more clearly.
- When the face is hit by the sun, no problem.
- When the face is NOT hit by the sun (i.e. in shadow), no problem
- However when it is to turn into/out of the shadow, SU probably does not know what to do with it and produces similar flickers like the shadow bug used to be.
Nice catch!
The SU Team will love it!

Fantastic! I'm not going crazy...
Thank you for following this up Gaieus

It does not seem to be new in version 8 however. I get the same when I export from 7.1, too. I ave never noticed it before though...

Hi Grice/Csaba,
This is indeed a valid bug that was introduced with 7.1 and something we found too late in the game to try to fix for SU8 M1. It is different than the shadow bug and occurs with animation export, but is not visible when viewing the model. We have it in our bug database and it is in the queue to be evaluated for fixing.
I'll add this thread to the bug. Thanks for reporting it!

Tricia,
I realise this was reported a while ago but is there any patch or update in the wings to fix this problem? I can't really offer animated walk-throughs to my clients when this problem is still occurring.

Hi Grice,
This bug has a high priority, but I don't know when it will be fixed. I will, however, bring it up again and lobby for it. I believe it is a complex, risky fix which makes it harder to put into a maintenance release, unfortunately.
Regards,
Tricia

Hi Tricia,
Thank you for the update. It is an odd problem and I hope that the team can sort it out soon.
Kind regards

Hi everyone,
I have also experienced this problem through the native Sketchup animation exporter.
However, I found an animation export using 'SmoothStep' plugin doesn't seem to render the flickering.
Smoothstep does it again, THANK YOU WHAAT!
Unfortunately for me I have a long animation and the 'Smoothstep' animation doesn't seem to stay smooth for long. The first few transitions between scenes look great, but then the camera begins to jolt (at the start and end of the transition). Maybe this is just me?
Could the SmoothStepAnim.rb be modified so that the animation has uniform (not smooth) transitions?

Thank you Tomdubbs. I only just came back to this post and saw your solution. Excellent! Just trying it out now...

I had this problem as well - similar to a "face-fighting" kind of artifact where the software can't decide which face takes precedence, except with a shadow. When the "sun" is coming straight across a face, the software can't decide whether to show it shadowed or not (thus this artifact).
This shows up on Face-Me components because as the camera travels around the model (if it is roughly 90 deg. off from the sun position) the Face-Me component is rotating to face the camera, and at some point it will become perfectly parallel to the sun's rays. -
Back in 2011, I reported this bug and Tricia S of the Sketchup Team said it was a high priority bug fix. But even the latest release of Sketchup 2016 still has this random artifacting problem on face me components when generating an animation.
Hard to know what to say really. Some of the inference improvements in SU2016 are great; but this problem with the standard export animation is a real disappointment. Smooth-step plugin - it is alright but has a few bugs - has a tendency to get stuck and take about 30mins generating the odd frame now and then which can seriously blow out rendering times. Do I need to export my model files back to SU7 to when animations were working properly?
I hate to be a whinger, but I and many other Pro license owners have sunk many thousands of dollars into the Google/Trimble coffers.
Can we please just get this problem fixed?!
