Hi all,

I have just bitten the bullet and purchased myDMX (two days ago), plus a ton of other lighting effects including the ADJ Nucleus, Revo 4, 2 x Equinox Domin8r's, 2 x Scantastic 4's, 2 x Dualizers, plus 8 x prolight colour burst floods.

I am giving myself the challenge of setting these up as accurately as I can in myDMX, and have made a perfectly colour matched profile for each of the channels of the Nucleus, (it doesn't help that the manuals for the Nucleus are not at all accurate, all of the colours are completely wrong other than off and white!), and a separate four channel module for the colour and pattern macros for channels 19 thru 22.

On the 3D visualiser, initially I have had to make do with assembling lamps 1,2 and 3 vertically, and lamps 4,5 and 6 inverted beneath them, to roughly give the effect.

It would be nice if there was a theta rotation for the fixtures so that effects such as the Nucleus etc could be easily modelled.

The included Nucleus model is a real disappointment.

Anyhow, after a bit of consideration, there is some good news!!!!!

By default, the 3D visualiser opens up with an plain gantry ready for population, if you try and build a dominator for vertical mounting onto this gantry, the lack of theta rotation prevents this from working.

What I did, was to simply clear the stage, and then flipped the whole stage on it's back, using the floor now as the back of the stage.

After constructing a perfect colour matched scanner for each of the six Nucleus channels, it was now just a case of setting the pan and tilt mirrors to midway on all of the units, and rotating each so that they faced directly away from the floor, (so all the mirrors are facing you). Then, I rotated the z axis so that all of the units were at 60 degrees to each other, and then overlapped the body of each scanner housing, so that I even ended up with something that resembles the Nucleus in every way, (apart from the behaviour on the four additional control channels from 19 to 22.

Theta rotation would however be a much simpler solution, but I hope that this helps shed some light on anyone hitting a wall trying to model your fixtures in the 3D visualiser.

I do have one question though, as I anticipate problems when I try and model the Domin8r, as the channel configuration on this device has all of the tilt motors from channels 1 to 8, and the colour macros from channels 9 to 16.

This prevents each lamp being modelled as a simple device, as the channels are not consecutive for each, i.e. ch1-tilt1, ch2-colour1, ch3-tilt2, ch4-colour2.

It is a real shame that there isn't a channel mapping function that lets you assign specific DMX channels to each slider, as would be the case on a professional dmx controller desk.
Hi Jingles,
Other than the 3D visualiser model of the Nucleus, the problem that I found with the profile for the current Nucleus device, is that all of the colour profiles are wrong.
You can be forgiven for this if it was constructed by referring to the manual, as this is also wrong.
So, what you have produced is probably a pretty accurate interpretation of the information that was presented to you.
To justify the above, and to reinforce my comments about making a colour perfect model of the Nucleus, here is what I did:-
I had the Nucleus set up, and had one of the channels aimed at a white wall.
Moving the channel fader one step at a time, shows precisely how the colours are mixed in the unit.
There are only three LEDS in each lamp, which produce the range of colours according to their combination, and intensity.
The first preset is black, then you get the single colours, RED, Green and BLUE, (Can't remember the order, as I am not by the kit).
All of the other colours are made up of only two of these LEDS, one of which is full on (255), whilst the other steps through five levels of intesity (50,100,150,200,255).
So you get RED(255), GREEN(200), then RED(255), GREEN(150) etc.
There is one additional preset before white, which is RED(255), BLUE(25).
If it helps anyone, I will produce a list of all of the settings for each of the presets, as I would imagine that this is going to be the same for a whole range of fixtures.
Even without using the 3D visualiser, it makes a lot of sense for the fader channels to be showing the correct colours.
I will post the list shortly, and would be happy to send you the nucleus model too, if you give me your email address etc.
Regarding the next software release, do you think that theta rotation and channel mapping could be considered, as they are both pretty simple features to add, (from a programmers point of view).
