Ignition PAR fixture profile not working correctly

"Brightness" is not Intensity, it's part of the colour picker which uses the Hue/Sat/Bright colour space.
Fixtures are always set to "Open White" when sent Home, as having a light home to 'black' would be very annoying.

What version of Eos Family are you running, and did you use the library fixture or create your own?

I'm guessing you mean the Ignition - Studio Par Platinum fixture.
If that's correct, in Mode 4 this fixture has an Intensity attribute on DMX offset 5.

I've just tried this here and it seems to be working fine.

Are you sure the fixtures themselves are in Mode 4 and not some other mode?
- These fixtures are just "RGB" without an Intensity attribute when in Mode 3.

Yes it is the Studio Platinum PAR in mode 4.

My software version is: 2.0.0.9.0.149

I figured it out. By turning RGB parameters down the light goes out. But the "intens" does not do anything.

I think your lights are not actually set to Mode 4.

From the description of the issue, the physical light is actually in Mode 3, where it does not have an Intensity parameter at all.

The mode the fixture is set to has to match the mode chosen in the console, or it will not work correctly.

You'll need to either change the fixture into Mode 4 as you originally intended, or if that is not possible you can use the Mode 3 template in the console.
