After loading Image, how to go back to preview.

Kabkee

<preview> shows before <image> loaded.

What I ask is that.
After <image> loaded, is there a way to load <preview> back and load <image> again?
It's like toggling <image> visibility.

I've been thinking a create a scene with no <image> but <preview>
are toggling two scenes only way to implement so?

Hi,

no sorry, there is currently no option or setting for a preview-only rendering...

But you could do that - add a xml-if check to the <image> element like this:

Code

<image ... if="!previewonly">
  ...
</image>

and then just 'reload' the current scene and set previewonly=true before:

Code

set(previewonly,true);
loadscene(get(xml.scene), null, MERGE|KEEPVIEW|KEEPMOVING|KEEPPLUGINS|KEEPHOTSPOTS, BLEND(0.5));

Then the <image> element will be skipped when loading the scene and so only the preview will be shown.

and to switch back:

Code

set(previewonly,false);
loadscene(get(xml.scene), null, MERGE|KEEPVIEW|KEEPMOVING|KEEPPLUGINS|KEEPHOTSPOTS, BLEND(0.5));

Best regards,
Klaus
