Weird HSB Slider behavior


#1

I’m getting really weird “shaky” behavior from the HSB sliders (and CMYK sliders) when changing an object’s Display Color (to custom). Can someone else verify this?

Thanks, I see this too. Filed as http://mcneel.myjetbrains.com/youtrack/issue/MR-1912

fyi, I’m still getting this bug in the latest Mac evaluation build.

Same here in RC2… the bug is still open.

Hello all - I’m having the same problem today with my CMYK sliders in Rhino for Mac 5.3.1
The problem just started for me this afternoon, has been operating fine until now. I use OSX El Capitan 10.11.5

Has anyone figured out what’s happening here? I need to specify object colors for an environmental design project - currently having to translate the CMYK values into HEX values, but this is not ideal.

Thanks!

Hi Corrie-

Sorry about this. This bug has been reprioritized and we’ll take a look…it may not be something that we can easily fix before the next release, but we’ll do some more investigation.

There’s OS X 10.11.6 as an update.

Corrie-

Unfortunately, digging into this a little deeper, it looks like we don’t have an easy path forward. Right now, Rhino stores color values as RGB values and - when converting to CMYK - these values don’t get converted properly. This is a problem, no doubt, and one that needs fixing. However, we’re going to have to look into a better solution for this in a cross-platform way (this problem is not specific to Rhino for Mac as far as I can tell). I know that’s a rather lame answer - this ought to be easy! - but I just wanted to let people know that converting “by hand” will be the only workaround in Rhino 5 for Mac right now. Rhino 6 for Mac may be another story.

Thanks Dan,

It’s a bummer that there’s no easy fix, but I understand. Oddly, it’s an
intermittent problem - maybe that makes more sense based on what you see
backend.

Best,
Corrie
