[Plugin] Export 2d with Alpha

Pixero

No - I have no control of how it's generated. As you see from the sample I posted the shadows even comes from the whole model, not just what is visible.

This can help for a shadow pass: http://rhin.crai.archi.fr/RubyLibraryDepot/download.php?file=displaytemplate.rb

And maybe a modification of my Shadow control script (http://www.pixero.com/downloads_sketchup.html) could be made to set everything not selected to: e.casts_shadows = false

Congratulations - one of the best for su 2d app

Hey, I did not see this, great plugin, thanks Thom!

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?

Have I put something in the wrong spot or something cause when I go to view/export 2D the settings comes up but then it doesn't give me a file type to save it as?

After the Settings window and you click OK you should get a File Dialog asking you what name to give the file. You must specify the file extension yourself.

I know and it doesn't give me any file type to save it as at all.

thomthom

You have to type the file type yourself - there is no list of file types because the SketchUp Ruby API doesn't let me provide one.

So if you want to save a jpg file just enter "myfile.jpg" in the file dialog.

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...

That baffles me. I have no idea why this happens. Exactly the same works for me...

test1.zip

Gaieus

Well, sigh... I can always use LO for exporting png's with transparent background...

Maybe it's an XP thing?

thomthom

I don't know. Haven't got an XP machine at hand right now. Could be an SketchUp bug...

Gaieus

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!

thomthom

I get Transparency with Sky on. But not with Ground.

...Gaieus... do you have the Ground on?

thomthom

Correction: Sky do appear when exporting. I just always tried with a view looking down so no sky was visible.
