Edit; to me, it does not export with transparent background... Nor does it export only the active context.
What version of SU did you use?
Got a screencapture?The most recent one; SU 8.
Here is a screen capture; now with a different codec than the one you could not open the other day if you remember...

Well, sigh... I can always use LO for exporting png's with transparent background...
Maybe it's an XP thing?
-
I don't know. Haven't got an XP machine at hand right now. Could be an SketchUp bug...
-
Well, you know where to report it (and who has all sorts of machines). I have no clue about the ins and outs of ruby. I could never make a proper bug report on plugins!
-
Just to narrow it down to a simple test case - can you try this one-liner?

Try what? Enter the ruby console? I get this:
-
If you set the background color to be 0,0,0 [pure-black] then the image will export with a transparent background in place of the 'pure-black', when you open it in Gimp or a web-browser etc you will see there is no background...

Should not need to do this - I export with the default SketchUp Sky - still I get transparency.

That's not entirely correct... iIF you have a Sky and/or Ground ticked in your Style you will not get a transparent background to the png for the areas that these parts 'cover'.
BUT if you have the Sky AND Ground un-ticked in your Style then I agree - the color of the Background itself is irrelevant because whatever it is when the have the png export transparency set 'on' that background is made 'transparent' - no matter what color it is - white, black, magenta or anything else! -
I get Transparency with Sky on. But not with Ground.
...Gaieus... do you have the Ground on?
-
Correction: Sky do appear when exporting. I just always tried with a view looking down so no sky was visible.

I find that both sky and ground obscure my png's background transparency ?
I need to have sky and ground both off to have a fully transparent background in the png, BUT even then shadows on the ground-pane will show up floating is space so you need to have that option off too... -
Don't know why I haven't seen this gem before today...
Awesome, Thomas...!
Thank you SO much...!! -
Hi Thom and TIG; you are right, when I turn ground and sky off, I can export with transparency.
And now I am banging my head to the wall (where is that smiley?
)This is exactly the way you need to set your style to be able to export your png with transparency!
-
Yea - we need that smiley.
This has been one for my Duh! list as well.
-
Thanks anyway (and again) for the plug however. I do not know if there is a solution in ruby but if not, I guess you have already updated the info on the first page.
Maybe a solution to temporarily disable ground and sky?
-

Maybe the user want either one on/off...
-
Thom,
This is exporting for me? Ground/Sky off, BG is White and adding .png to file name when exporting but no joy! I know i've missed something here but re-reading the thread i can't pin it down?
-
Can you post this joyless model? And/or screenshot?
