Matrix Model is all White

[Chris A]

I know this is something I'm missing.

I have my matrix set up as a model. No matter what effect I place in the sequencer, the matrix just shows up as all white. The matrix shows up when it is supposed to, but it's all white. What simple mistake am I making?

Thanks, Chris

Check Dimming Curve - should be 0s versus blank (or remove from xml completely).

I checked my xml and it was incorrect. I changed them to 0 and I still see all white. I really thought that was the problem. I have attached my xml file. Thanks for the help.

your dimming curve for your p10 model has R,G,B Gamma's set to 0.0.
Why?
Normal is 1.0

As soon as i changed the dimming values to 1.0 and dropped a butterfly on to your model, it displayed correctly

Because he was told to 2 posts ago.

I recommend this thread be updated so it won't cause confusion for somebody else.

James is correct I was following the advice from another post referenced above. I'm not sure how the dimming value changed to begin with because I wouldn't have messed with it, since I don't know what it is and how it affects my model.

It is working now. Thanks everybody.

Ok, I see. The post that was referenced was talking about brightness and gamma being blank and to restore them to original values they need to be zero and one. Mararunr only picked "blank" goes to a zero, where the complete answer is default brightness is zero, default gamma is 1.0.

(Referenced link:)
      <dimmingCurve>
        <red brightness="" gamma=""/>
        <green brightness="" gamma=""/>
        <blue brightness="0" gamma=""/>
      </dimmingCurve>

Whereas this is what it should look like by default:
      <dimmingCurve>
        <red brightness="0" gamma="1.0"/>
        <green brightness="0" gamma="1.0"/>
        <blue brightness="0" gamma="1.0"/>
      </dimmingCurve>


I didn't need to edit the xlights_rgbeffects.xml file to fix your issue, I went into your P10 model and clicked dimming curve and put in 1.0 on gamma. For all my models (I have 80), I never touched the dimming curves on them. Dimming curves can fine tune your display elements.

Sorry for the confusion

Yeah I believe the problem is a user clicks the dimming curve button out of curiosity but doesn't actually change the values and it causes it to create invalid values in the xml file.  I mentioned it to Dan and I believe he was adding a check on those values but not sure if it got done or maybe its done but just not in a new release.  We need to double check it.

And my apologies for adding to the confusion.  Was only trying to help.  Glad to see Gil's post where maybe it will get checked in a future release.  For me, I have gone back to version 4.2.24 for now (the one I used for this past season).

That's exactly what I did.  See you in Vegas. Come on March.

Why would you go backwards?  Dimming curves were added way before that version and there's been nothing but improvements and bug fixes since then.

Because it works without issues for me.  I put together a new 3x3 P10 matrix in the lab/garage and had issues with the newest version (similar to this thread and others).  Spent two hours thinking it was wiring on my part, then thought about reverting to the previous version I used during the season and voila, it worked fine.  I have since read about the gamma/dimming and have not gone back to try again.


It's not affront to the hard work that you all do, it's just what worked for me.  It's a suggestion to try something different when there's a problem.  It was much easier to try a previous version than the 2 hours of wiring and rewiring trying to find the hardware problem.


Just my opinion.


Hopefully this weekend and I go back and try the whole dimming/gamma thing and see if I can use a new version.

[Gilrock]

In all likelihood going backwards wasn't what really fixed the problem.  I really don't want anyone thinking they should install an older version that just causes more problems for us.

[Gilrock]

Everyone should also be aware that going backwards and then forwards can also have unintended side effects.  Sometimes we add code to detect older versions of files to make adjustments to an effect.  We don't normally have code in there to handle a newer version of a sequence being opened in an older version of xLights.  I'd have to test I'm not sure what we do with the version number.  If you open a newer sequence in an older version and hit save does it end up with the older version number in the header?  If so then that would cause any effect adjustment code we've added to run twice.  Many times when we make changes to effects we have code in there that detects older sequences and then runs a conversion to adjust the effect to the new changes.  If you jump around versions I'm afraid you may get those adjustments multiple times.

Thanks for the advice Gil.
