Null Pixels in the Middle of a Model

[kentd]

Hi I have a question in regards to needing null pixels. I have a starburst defined as a custom matrix with 225 pixels, 30" tubes with 9 pixels per tube I am going to need to break this into 2 strings one 90 pixel string and one 135 Pixel string with 3 null pixels in each string. The model defines this configuration as a 225 pixel model with a total of 675 channels. But essentially you have one string as 279 channels and the next string as 414 channels for a total of 693 channels but only 675 that are the actual model leaving 18 channels for the null but they are split, how do you deal with this so the effect will be correct?
The reason for the first string being only 90 pixels I am thinking of using a FireStick that would have 60 pixels to be in front of the the first string, with the controller feeding the 60 plus the 90 for a total of 150 on that universe.
Thanks
Kent

I've never used null pixels so maybe I'm wrong but I thought you basically would setup your hardware controller to know where you have null pixels and it would correct the data as needed on the fly and the sequencing software is unaware of their existence.

The hardware controller does have the null pixel capability and puts them at the beginning of the string so what you are saying about the software would seem correct and make sense. Thanks.
