Quote - Ok, I'm back.. it's now been 11 minutes and no .png file.  I have yet to see in the log file that one has been written.   Do I need to wait longer?

I have got the .lsx .lxs thins reversed a few time - I almost always have to make a new file name after as the .png did not write.

 

so name it reality_scene_b.lxs and reality_scene_b.png in the output tab and see if that works.

 

Not sure if the file gets curupted or what, but that fix worked for me.
