I had two 100 frame sims from Embergen (image sequence TGA) importing into Illugen.
Start frame 0, 100 total frames, Looping set to enabled.
I channel packed relevant data into a single RGB texture and set to export.
Export: First Frame 0, Number of Frames 100, set directory and filename (name_packed_###.TGA).
Upon importing the new set of image sequences, I noticed a hiccup in the flipbook.
The first frame was “bad”, like it was a frame from a different slice of the flipbook.
