Rhino 9 WIP Display modes transparency issue

Serengeti (Rhino WIP)
1

There seems to be a problem with display mode transparency.

Starting with a simple box displayed in shaded mode, I turn off Surface isocurves in the Display panel. The problem can be fixed by going into the options and restoring the defaults for the display mode.

Doing the same thing in Ghosted mode makes the object disappear and here you can also see a proof in the display mode options. Transparency is set to 100%. All this just by turning off isocurves.

I see that, thanks for reporting
It looks like every change in the display settings does that. I think the transparency spinner in that dialog is busted because you cannot change it (reverts to 0)

PS: For the time being the workaround is to set the transparency in the properties page after making the changes you want to the display mode.

That does not seem to work for the Shaded mode but anyway thanks and I’m looking forward to having this fixed soon hopefully.

@Gijs
I posted this Shading seems broken. 5 days ago, Don’t know if it’s related to the same bug…? [mac here] But I can’t get my shaded mode to shade at all since then.

thanks a lot

Yes, that is the same problem. It is now fixed. Next v9 Wip build includes the fix.

I see the next problem. The “modified” highlight color in dark mode…

Some background. I rewrote all Display Modes pages. They used to be native implementations, so we had to code everything twice when adding options (implement in Mac and Windows). Now we have only one implementation and both Mac and Win uses same code.

Btw, now is the time to suggest dark/light/Win/Mac modified color. The color that show that a setting has been changed.

It’s just as terrible in normal mode. I think a less saturated blue would be fine. It wasn’t bad in Rhino 8

Hi Max -

I’ve moved the following to your list.

As Martin notes, it used to be fine in Rhino 8, no?

Yes, that is correct.
