Text mapping to Matrix Group problem

[johnty]

I have a 28x56 pixel physical matrix divided into two models, MatrixLeft (800 pixels) and MatrixRight (remaining 768 pixels).  These two models comprise the Matrix Group model.  I did this so I could set separate dimming curves for legacy Ray Wu pixels and new ones bought this year in which they changed the manufacturing process resulting in different white balance between the two halves of the matrix.  After calibration, the colors and white balance are essentially perfect and my sequences play normally with some effects on the Matrix needing a Render Style of Horizontal Stack and some needing no change from Default.

The only problem is the Text effect, rendered as a Horizontal Stack, where pieces of letters disappear when they are on the “seam” of the matrix.  See MatrixGroup attachment.  In column 29, the 800th pixel on the left side ends the model and one row above it pixel 801 starts a new 100-pixel string.  A custom model was created since all strings except the last one are 100-pixel and they mostly terminate somewhere in the middle of a column.

The Text effect can’t display pixels of a letter that occupy pixels 785-812, the column that logically joins the MatrixLeft and MatrixRight models.  See MatrixRightModelLayout attachment.

I’ve attached the test program showing this issue.  Depending on the type font style and size, moving the text with the ‘X’ Start Position slider sometimes helps avoid the missing parts of the letter, sometimes not.  Maybe it’s a layout definition problem where the folks on the Zoom call helped me set up the start and end channels of the two matrix pieces but other effects play across the physical matrix with no problem.  I do get a warning about what I’m doing…

Effect problems
    WARN: Text effect generally does not work well on a model group.

Perhaps this isn’t fixable.

Yeah that matrix is never going to work as a group ... why do you need to model it as 2 rather than 1 matrix?

I didn't know that vendor had changed color balance of "new model" pixels this year which I used to build right half of the matrix.  Had to make two models to set different Dimming Curves for each side to make entire matrix look like the same pixels were used throughout.

Text effect is the only casualty of doing a model group.

What controller. Can you apply dimming curve on the controller. Or in the player.

Controller is a Falcon F16v3.  Dave Pitts said there's no way to adjust individual red, green and blue sub-pixels, only at the macro level.  I'm using a Pi and FPP for the show.  There was talk of having sub-pixel dimming curves in 2.4 but it hasn't happened.  Attached is the dimming curve I'm using for the "new and improved" pixels to match the others.  I don't know of any other way to make all of the lights look the same.

Yeah. Looks like it is what it is then.

If you were to make another model (a Ghost or shadow model) that is the size of the two matrices combined, make sure they are the same channel numbers, and put an effect onto that model, would that work?  Putting effects on that would render properly, and show up on the original.  But not sure how dimming would work with overlapping channels on different models, so maybe it wouldn't work.  Something to try however.

Pretty sure the dimming curve is used when the effect is rendered which means it only uses the dimming curve for the model the effect is on.  Otherwise we wouldn't know which dimming curve to use if you had several models pointing to the same channels or overlapping models.
