Really Basic Universe Math Question

[danj]

I have a really basic universe math question.

I reset some of my models tonight and now I am seeing the 1st half (left side) of the 3m megatree displaying the effects intended for the arches and the other half displaying the effects intended for the 3m megatree.

Arches 1-6 channels 511 thru 870 (arches are 2m long each, originally 30 pixels/m reset to 10 pixels/m)
3m megatree channels 871 thru 2310 (it is 16 sets of 3m strips, originally 30 pixels/m reset to 10 pixels/m)
5m megatree channels 2311 thru 5310 (it is 20 sets of 5m strips, always set to 10 pixels/m)

What am I missing here??  I KNOW this is going to be easy but it is sure not jumping out at me.....
Thanks.

Were did you reset your models from 30 pixels/meter to 10 pixels/meter?

In xLights only? On your controller?

[MrChristmas2000]

The next question is what are  you using to test your lights.

1. a sequence created in Nutcracker?
2. xLights test tab?

If you are using a sequence and have not re rendered the sequence then the original channel effects are still in place and will show up on the wrong elements.

I am only "watching" the layout tab so far.    Doh.   I didn't think about re-rendering.   I will do that and re-check...   I plan on hooking up one controller and the lights for one of the megatrees that I will just set on the floor tonight or tomorrow night so I can make sure all my universe info is correct in XL/NC and controller.

Update--I rendered a few sequences and all is well now.  Phew! Relief!!

Thanks very much

[danj]

Update-- I have re-rendered several of my sequences and have now hooked up about "half" of one megatree (not enough room on the floor for the whole thing...) and have run those lights using xlights' output to lights.   What I am seeing on these sequences is that megatree "#2" is displaying the effects that I set on megatree "#1".   I have a fireflies sequence in which I turn on the megatrees at different tImes, so it is really obvious that megatree #2 is coming on and displaying the effects that are intended for megatree #1.   I have checked & re-checked my channel assignments, and I even purposely set megatree #2 to start at the first channel of universe #5 instead of just sequentially following the megatree #1 channels.   I think I need to do that anyway because I am running megatree #2 from a different E682...   Oh, by the way when I am watching the progress of the rendered channels at the bottom left of the screen, I am not seeing my megatree #2 ever get rendered.  I even recorded the process with screen cast so I could watch more slowly and I did not see it.    Any ideas???   THANKS!!!!

Post your files or screenshot of all the relevant setup.  You have something defined wrong.

[danj]

Thanks Gil.   Here are relevant files.

Did some more troubleshooting tonight using xlights test function and SACNView to generate test signals, because even though I have re-rendered & re-saved sequences, I am still getting my 2nd megatree displaying the effects from my 1st megatree.  I changed the channel assignments for my second megatree to make 100% sure the channels did not overlap with the first megatree's channels.   I checked the channel assignments by doing csv exports for both elements and the channel assignments are correct.   When running a test signal from xlights into the first channel of my 2nd megatree, the first channel (3570) turns on the universe 9 channel 1 LEDs (.   When I generate a universe 7 channel 1 test signal from SACNView and chase it up the strip, the 1st LED on my first strip illuminates then the rest of the strip chases as expected.   I downloaded the most recent xlights version today in case my copy had gotten corrupted or something, but that did not make any difference in what xlights is doing.  I still think I have some type of weird rendering thing going on because I am still not seeing my 2nd megatree indicating anything at the bottom left when I render or save.   I'm stuck here...

[Gilrock]

Can you give me a timestamp where it's not right?  I opened it up inspected the models.  I unchecked the Individual Start Channels boxes for both mega trees because it didn't look like you had any gaps so it was unnecessary.  I went to sequence tab and then hit the Green Gear to render.  Everything looks to be playing fine for the first 30 seconds.

[danj]

Gil--thanks again for looking.    The displays as shown in xlights look fine, but when I power up real lights, then I am somehow getting incorrect universe assignments on my second megatree.   "megatree5m" is the one giving me fits!!!   I posted some troubleshooting results tonights--compared SACNView-generated test signals to xlights and it looks like xlights is "off" by two universes...   I will keep messing with this tomorrow night.   Gotta get some sleep....

[Gilrock]

Dan wait a minute.  You were asked if this was in xLights or on the controller and you said I'm only watching on the layout tab so far.  So that meant you were having the problem in xlights not on the controller.  Now you're saying its ok in xlights but wrong when played on the controller.  If that's the case then you need to show screenshots of your controller setup.

Also I noticed you are using the bulk universe assignments in setup.  If you are sure the controller setup is correct then next troubleshooting step would be to try creating individual entries in the xlights setup for each universe instead of having a 32 universe block.  I know of at least one bug the bulk universe assignment was causing...just don't remember exactly what the bug was but I don't remember seeing it fixed and now that message is buried deep in history.  Hope it was logged on Github.

[danj]

Gil--I'm not sure what a bulk universe assignment is (?).   I can't send a screen shot right now, but my setup is that I have the first universe setup as a COM1/LOR universe blocked out for AC (LOR) channels, then I have E1.31 universes setup from universe 2 thru 15, all set as multicast with the last channel 510 on each universe since I am using an E682....

The first night I noticed the problem, I had not yet hooked up a controller.   Once I rendered, xlights was happy.   However, now that I have hooked up one of my controllers, I am physically seeing the problem on the lights but the displays in xlights/NC are correct.  Fortunately, on the "fireflies" sequence, I am applying NC effects to the megatrees at different times, so it is really obvious that my megatree5m is receiving my megatree3m data stream for some reason.

As I noted last night, when I send universe/channel on/off signals from SACNView software through my controller to my lights, everything works correctly (e.g. when I tell it to turn on universe 7 channel 1, the first three LEDs light up red on the first strip, etc), so my controller is setup correctly.   I am telling xlights and my controller to start my megatree5m model at universe 7, so the two should be synched up in that ballpark.

I will keep troubleshooting when I get home tonight.
Thanks for your help!!!!!

I looked at several users sequences last night so maybe I got mixed up but I thought yours was the one that had only 2 lines on the setup tab but it defines 48 universes.  That's what I call bulk definitions.  You can create universes where its one universe per line.  I have tried the method where you create a chunk of them.  I can look again tonight to see what I was remembering.

[Gilrock]

Ok yeah I was thinking of a different user's setup.  You don't have any of the bulk assignments.  So I guess we just need to see your controller setup.

[Gilrock]

I looked at your setup again.  You have MegaTree3m starting at 871 and MegaTree5m starting at 2550.  In your setup 871 starts way in the middle of a universe and 2550 is actually the last pixel in universe 5.  You need to show us how things are physically wired.  I usually have all my elements starting at the beginning of a universe.
