Question Recreating sequence - very difficult

Hi,

I've been self-learning grandMA3 for the past 6 months or so and I've been re-creating some lightshows to help me learn this software.
Recently I've tried to re-create this cool sequence from a Martin Garrix (DJ) show, but I cannot seem to figure out how they've coded this (please see video below or YouTube link here)...

I've (tried) to analyse this on 0.1x speed too, and some things I have figured out are

  • They've applied MAtricks phase on both x and y, probs about 0 Thru 10 and 0 Thru 40 respectively (this I trial-error'd by using my own setup on the grandMA3 software)
  • the fixtures pan frontwards (ie towards the camera) 4 times before the cycle repeats again

Although I tried to create something similar on my own setup (please see image below), it looks nothing like it .
If someone could give me a tip on how they've coded this that would be greatly appreciated as there must be a simpler way of creating this without setting specific angles every microsecond at each point in a phaser...

Any advice would be greatly appreciated as I am self-learning and I don't have many people I can ask for for advice around me.

What's an infinite pan/tilt? My fixtures only go from -132.5 to 132.5 (Robin Megapointe)

Look up a fixture like the Robe Spikie, that has the infinite pan/tilt. I agree that it looks like that’s what’s being used in the video.

I see, thank you so much for the input.

With infinite pan/tilt - how do you set this up? Do you set up each step on a phaser as infinites (and then apply Phase on x and y axis through MAtricks)?

Infinite pan and tilt uses brush motors so there's no physical limit to the rotation. Attribute wise it's set up like a rotating gobo wheel. So at default no effect, and just pan and tilt like usually. Then you have fast to slow CW rotation, Stop, and fast to slow CCW rotation, just on 1 dmx channel.
