I have a sculpture that has one dead pixel (only lights green LED), which I do not currently want to replace the strip for. My pixels are mapped manually using points in 3D space. Is there a way to not skip the pixel, but just make it dark, in all patterns? I would like to keep the 3D pattern unshifted to compensate for the dead pixel. I will replace the strip segment at some point, just not before an upcoming event.

Thanks!

Without touching the map, easiest is to add a small bit of code at the top of render for every pattern. Like  
“if(index== 42) return rgb(0,0,0)”

Pixelblaze doesn’t have a skip/ghost pixels option.

Thank you! I will test this out tonight!
