Open the Artnet HUD and go to the 2nd tab: Universe Map
Left column is PixelMad ouput, Right column is Artnet Universes (centre column is broadcast / unicast)

Assuming that you've patched the fixtures to Pixelmad Outputs 0 & 1, then you should change the Artnet universe (right column) to 16 & 17 on the top two lines (PixelMad output 0 & 1

Also ensure that DMX Output is enabled in Pixelmad.



Are you trying to merge both MA and Catalyst? - or just use Catalyst?
Artnet supports HTP merge - but you may require an Artistic Licence product to enable it

Else - Do send me a zip copy of your show folder
(exclude the catalyst app - but let me know which version)
Alternatively - just a screenshot of the pixelmad window and the artnet HUD (all 3 tabs)
and I'll take a look and see if i can advise...
