DMX In / ChopToTop Rendering error

Bugs
1

I am trying to take 1 universe of DMX data (specifically 345 channels) from ArtNet and turn the channels into RGB data for pixels. Everything works as expected, but I’m getting an inconsistency when converting from a CHOP containing the 345 channels to a TOP. When rendering the TOP data, the chopto op flickers between the expected 1 by 115 pixels and an unexpected 2 by 115 pixels. I know I could interpret the CHOP in a different way, but I’m wondering if I’m doing something wrong or if this is a bug?

You can try to force the bug by previewing any of the TOPs and making them larger or moving them around.

The DMX In CHOP in Packet per Sample is timesliced, meaning there may be more than one sample per channel, such as in the case when there are frame drops.

If you only want the latest packet then “Packet Per Channel (Latest)” might be a better option.

Of course, thank you Eric. So this isn’t a bug. Feel free to delete or archive if needed.

I couldn’t figure out the (Latest) option so I just did this instead:
