(1809)Bug Report: Update not working as expacted

Hey Roman,

Thanks for the report. Just to be clear, you only updating a cue, right? Not trying to update a palette at the same time? Are you working in CMY or HS or both?

I am baffled by the fact that an effect would look fine in the programmer but not when recorded into a cue. If you change the fade time to 0s on that cue does the "visible offset" go away?

Dear Chris,
thanks for your fast relpy,
I'm only working with CMY no HSI
Yes to your first question I'm only updating a cue with a different color information.
To your second question, yes to offset goes away. Very confusing:confused:

Hope this helps.

I will have to setup this kind of test situation here in Austin and see what I can dig up. The first problem is probably logged already in some fashion but that second problem sounds like an engine problem that might need some investigation. I will keep you updated.

Thanks Chris,
if you want I can send you the showfile.

Cheers Roman

Hey Roman.

We have started to reproduce your first issue here in the lab and can the see problems when updating colour values in large RGB LED cues. This actually looks like a problem that starts with grabbing fixtures from stage and touching them and changing their values. This is primarily a mutexing problem that has probably been around for a while. More concerning is a problem we're seeing with unwanted offsets (fanning) being thrown into a large selection of fixtures when changing their values using the encoder wheels. We are working on logging a defect for this and I will post our results in this thread.

After reproducing and speaking with development about the second issue you reported, test has learned that this bug is incredibly difficult to overcome because of the lack of DP syncronization in the system. Since go messages being sent throughout the system reach one DP slightly before the other, what's happening with your playback is that the OBs are calculating these large fades just slightly out sync with one another which results in a slight offset in output. This becomes more obvious with large quantities of fixtures, especially when running effects on RGB LEDs. This kind of programming exposes a limitation of the current system; one that will more than likely have to be overcome with hardware in the future. This is probably not what anyone wants to hear but it is an honest assessment of how our desk currently performs. Wholehog users can rest assured that looking forward we are acknoledging the challenges that large, individually controlled LED rigs bring to lighting desks and working on software and hardware improvements that make these kinds of shows easier to control.

Okay Chris, that means that I have to live with it like it is.
But it's good to hear that you and your guys were able to repro my problems.

BTW: Showguns arrived I'm very impressed:147:

If you need any further information you can contact me any time.

Thanks Roman

Roman,

Not to throw a wrench into your show, but would there be any chance of doing a pixelmad type setup since you have over 1000 LED's? It would definitely help the console deal with that large rig.

Just curious more than anything...I seem to be falling into the same realm occasionally. More than about 100 LED's, I end up using some type of pixel system to relieve the load.

Jon we thought about that, when planing the show but it ended up that a console would be better. And it is.
I hope to get out pics of the show next week. Show is tomorow morning live on TV.

Cheers Roman

I figured it was something that you looked at, but I wanted to throw it out there just in case...

Looking forward to the pictures.

I posted a pic right now. Keyword "Kiddy"
It's only taken with the cam of my mobile.

P.S.: Yes these lights are Showguns

They ROCK

Roman

Maybe somebody is intressed in seeing pics of this event.
