Just encountered a quirk with VP16's Render As process. It's been working fine except that in between some renders, I opened another project in VP17 to check on how I did a certain FX sequence. After closing VP17 and continued working for some hours, I went to perform another render in VP16 … but … when I opened VP16's Render As window, VP16's Render As options did not appear. The 'Templates' window was blank, and the 'Formats' window only contained VP17's Render As options. To recover VP16's Render As options, I rebooted the computer - and this did successfully restore VP16's Render As options.
It's just something to be aware of if opening VP17 while working in VP16 and then using VP16 to render later on - assuming this quirk extends beyond my system.
