Matrix not displaying effects, just shows white pixels

[SventeHof]

Hi,

many thanks!!!
I try your file and it works.
Then i open the model -> dimming curves and the fields are empty .. then i didn´t press cancel but OK and this was messed up the state.
if i insert 1 at gamma and 0 at brightness again and press ok, the snowflake works fine.

So this could be the same problem as blakec has!

Maybe it´s a bug in the Programm, that the fields are empty?


I will rebuild the snowflake from Matt Johnson and therefor i need all the nodes ..
In the next step I will the stars and strokes Add as individual elements , so that they can be controlled individually  or as a whole.
Just as Matt also makes it :-)

I'm going to add to this topic as I am seeing similar results. However, with mine, I can get it to work if I use a group.

Here is my setup. I created 4 Vertical Matrices, 1 for each of my pillars. I then placed those 4 models into a group. So far so good. When I go over into the sequencer, I dropped the 4 pillars onto the timeline and noticed the same thing as the OP. My pillars were all white. Didn't matter which effect I chose. So, I dropped the pillar group onto the timeline. It worked as expected. All the pillars were now showing the effect.

I have attached a couple of pics to illustrate the issue. The first one should be the 4 pillars with individual effects (Fire) and you'll see that they are all white. The second pic is of the pillar group inside of the next set of timing marks. You'll see that all 4 pillars in the instance are displaying the effect as expected.

I wouldn't think that it would be anything in the way I set them up because then I wouldn't expect it to work as a group either. I have also attached some screenshots of my model setup. The 4 pillars are all the same except for the channel info obviously.

I doubt this is the answer, but from time to time my display preview window will have garbage on one or more models and the only way to fix it is to exit out of xLights and Re-Launch it.

I had another issue today where I have a rectangular section of my yard outlined in pixels.  I created four straight lines and then created a group containing all of them.  When I dropped a red/white marquee effect on the group, two sides were red/white as they were supposed to be and the other two sides were blue/white.  I expanded the node view and sure enough the color was blue in the data layers on those two sides.  I ended up just redoing all 4 models and the group and then they were all red/white.  I have NO idea why that happened.

I found out what was wrong. It was actually already mentioned by Gil but I didn't think it applied to my situation because I didn't modify my dimming curves. However, I did go into them just to see what it was. I then clicked cancel on the dimming curves screen. That didn't seem to matter. It still saved blank dimming curves in the xml.

In a prior post in this topic Gil said:

Do you know what you did with the dimming curves to get it into the state it was in?

You're file looked like this:
      <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>

Well Gil, I can tell you how to replicate this. In the layout, go into Models and modify a model. I've verified that it happens on a vertical matrix and an arch. Then click on dimming curves. You'll notice that the values are all blank rather than 0. Don't change anything. Remember, we're just here because we were curious as to what this feature was. Click Cancel in the dimming curves window. Click OK on your Model window and then OK on the Model List window. Finally, click Save on the Layouts window. If you go and look at your xml you'll see that the dimmingCurve element is now present (even though you clicked Cancel) and the values are blank rather than 0.

Once I removed the <dimmingCurve> element from the xml of my vertical matrix then everything worked as expected in the sequencer. I can only assume that the reason it worked when I used the group containing the vertical matrix is perhaps the group ignores the <dimmingCurve>?

Hope that helps.
