When I export a 900 frame animation, it is only rendering 720 frames. What am I missing?
Let me guess, you exported at 30 fps from 3dsMax, but didn’t change Vantage’s default sequence FPS which is 24? Vantage can render at different framerate compared to what was configured in the original vrscene. Double check the value in the “render sequence” dialog.
BINGO! You are right.
We don’t have the FPS info available in the .vrscene file as far as I know, but maybe we should add it, so we can change it automatically in Vantage when you load a .vrscene.

Definitely add it please! 
Turns out we do have the FPS info in the .vrscene file.
Our latest internal Vantage builds already read it, but we have yet to release a build with this change.

The build we just released (1.2.0) will load the FPS setting from the .vrscene file.
