Hi there, and sorry for this late reply. The best way to create fixture files is to do so on your own. There is a realy simple reason: you have the fixture at your side. An other reason is, you will not have to pay someone for doing the fixture file. The user in this forum will provide you help for free, if they can.
To get startet with fixture creator read in the Wiki about it:
http://www.freestylersupport.com/wiki/fixture_creator
If you already have some worke done, it would be nice if you can provide the current pff file (chose "export" in fixture creator) so we can take a look and try to find your problems.
Let's start with the simple dimmerpack. You can crate dimmerpacks in fixture creator but most user do not like it. The problem: you can only define one intensety channel per fixture. But the dimmer has some more. Intensety channels are use for master blackout so you want every channel to be defined. The solution: use a simple one channel PAR can for each dimmer channel. You will finde lots of theme in the fixture list. Be sure the addressing is done right! If you have a 4 channel dimmer with start address 5, you will add 4 simple par cans, first with address 5, second with address 6, third with adress 7 and fourth with address 8.
Not to the other fixtures you asked for. As I said already it is hard to finde your problems without a better discription what is not working (and what is) and without the current pff file. Please discribe your problems better and upload the pff files and I will help you to get this fixtures work.
