I started rendering an animation and didn't select 'Frames Output' but only 'Video Output'. Rendering took long time and I lost connection to the license server. KeyShot 9 was frozen to the state where it tries to save the animation.
I thought I lost all the frames but fortunately I found them from the latest of the multiple folders
C:\Users\myusername\AppData\Local\Temp\temp_ks_frames_1587550XXXXXX
