Quote - If the interval is set at 5 (300), then there should be a png by now.

Open the reality_scene.lxs file with a text editor, e.g. notepad, and see if there is this line about halfway down:

  "bool write_png" ["true"]

The interval is in seconds, so it should be 300 for 5 minutes.

is it the reality_scene.lxs or the reality_scene.lxm?  the lxs file only wants to open with Luxrender.exe

 

the lxm shows this.   I'm not seeing "bool write_png" ["true"]
