Help with animated Jpeg Sequence

[Gotschel]

I'm working on a project where I am using an animated imagetexture.

- I have the animation sequence saved as individual Jpeg sequence files.
- I've created an Octane imagetexture and loaded the first file of the sequence.
- Mode is set to Simple.
- Timing is set to Range.
- I've entered a Range start (2300) and a Range end (4650).
- I've entered the Movie Start Frame (107892) and the Movie End Frame (110314)... Frame Rate is set to 30.
- I've checked Animate Preview in "Editor".
- All images are in the "tex" folder.

I am able to jump to any frame within the 2300-4650 range and render a still image. When I do this, the images are different (as they should be), but when I render the clip, the animated texture does not animate.

I've been through several forums and can't find anything that helped.

Is there something I am missing?
