buddy parts?

I hope this clears things out for you:

For example, if fixtures 1

(release notes)

I read the release notes already as well as the manual. But the 'button' buddy parts does nothing to me. Tried a bit. But no clue what this might do.

Buddy is used like ist was before.
So a Buddy of 2 will give the Same values to two fixtures next to each other in your selection, eg. Fixture 1-10, Buddy 2, fan any value, 1+2, 3+4, ... will get the same value.
Same thing happening with fixtureselection when you press group+next/back

I think i am missunderstood in this.
I know how buddying and segmenting works. What i am looking for is the soft-button labeled "Buddy Parts" at the far right of the segment toolbar. You can press and unpress that button.
Hope thats clear now.

Buddy Parts enabled will treat a compound fixtures 'parts' as a singe fixture so fanning will NOT apply to the individual 'parts' that make up a compound fixture.
This setting is the default.

Buddy Parts disabled will treat a compound fixtures 'parts' as an individual fixtures so fanning will apply to the 'parts' that make up the compound fixture.

Easy way to look at this is to patch 2 Shapeshifters, and fan hue.
Now disable buddy parts and do the same, notice the 'parts' now have individual values

Hope this helps.

Ok. That clears things.
By the way... this button is not mentioned in the manual.
