Export as image no longer works with F5?

Q

Is it intentional that "Export to image" now only works after a render (F6)
and not a preview (F5)?

There was weird behaviour in previous versions where I sometimes had to hit
F5 several times before the correct image would get exported, but it appears
that now (since 2014.11.05 at least) attempting to export an image without
rendering with F6 results in an empty scene.

No, and it does work for me with the latest snapshot (on Linux).

ciao,

Sorry I should have been clearer. I tested with the latest OSX snapshot just
before posting - it is doing it with 2015.01.05

Could this be related to an issue I've had with previous versions where if I
wanted to export a number of renders using different colours, then OpenSCAD
would appear to export the render from the previous press of F5?

E.g. my workflow would be:

  • set colour("red"), F5, Export to image, call it RedRender.png
  • set colour("green"), F5, Export to image, call it GreenRender.png
  • set colour("blue"), F5, Export to image, call it BlueRender.png

but when I open up my files I find that RedRender.png would be blank,
GreenRender.png would be red, and BlueRender.png would be green, etc. I've
learned to get around this by simply saving RedRender.png twice before
moving on to the other colours.

Saving twice in this instance doesn't appear to make the render output
anything other than a blank PNG.

E.

Actually, ignore my last sentence. I just tried again with a canonical test
(50x30 cylinder) and though the first "Export to image" results in a blank
PNG, the second attempt (no re-render in-between) results in a correct PNG
output.

There must be something in my more complex file that is compounding the
issue.

Export Image is basically a screenshot of the current view port. So if
the view port is empty, the PNG will be too.

ciao,
Torsten.
