Error when trying to create a Groupmaster in 1.4 OnPc (Windows)

Does it happen with other groups, or other executors?

Same here blank show with a single group:

Assign Group 1 at Page 1 Exec 203

Assign Group 1 at Page 1.203

Swipy Assign, Touch Executor

Hmm. Works on a console. Perhaps this might be an onPC-only issue.

Are you using onPC for Mac or Windows? And do you have a command wing (or command wing XT) connected?

this seems to be a Windows only bug.

plausible workarounds:

1. Assign the GroupMasters on a non-Windows system, then load show on Windows computer

(loading a show with already assigned groupmasters seems to work)

2. Use Virtual Group-Masters

- Swipey>EditOptions>Mode

set mastervalue via the EditOptions' onscreen fader,

or by selecting the group via Select keyword, and using a fader with the Master "Selected"."Master"

or via commandline: FaderMaster Group xx At yy

3. Use WorldMasters instead of GroupMasters

seems that it is possible to bypass this error by assigning the group-object via Lua, instead of commandline or GUI.

Paste the text below into commandline or in a Macroline for later, and use whenever you need to assign a groupmaster to an executor on a windows machine running 1.4.0.2

Lua "local gIdx,eIdx=tonumber(TextInput('groupnumber?')),tonumber(TextInput('ExecutorNumber?'));Cmd('As Gr %i A Ex %i',gIdx,eIdx);GetExecutor(eIdx).Object=DataPool().Groups[gIdx]" 

Thank you Andreas. The Macro works perfect.

Yes, the Macro is a good workaround.

But I have the same issue on my onPC V. 1.4.0.2.

But I think it is reported to MA yet...?

Yes, this has been reported.

Hm, as I tried the Groupmasters with the mentioned workaround it seems to me, that the GM doesn't work for Fixtures with virtual Dimmers. I tried this with a simple LED Bar (after trying with another Fixture) with 12 RGB Pixels and the GM has no influence in 3D. I don't know how it looks like in "real life"... But in 3D, nothing happens to the (virtual) intensity...
