The render does not update when the timeline time changes
Hi!
I can't figure out why when using SmartRender() my render doesn't update when I adjust the slider on the timeline. The value in this line
A_long shift = in_data->current_time / in_data->time_step;
does change but the render itself doesn't update. When I use the deprecated Render() everything works fine. How can I ensure that the render is updated when the timeline time changes?
This code is supposed to shift the image to the right as the timeline time changes. It works with video, but not with images. Perhaps I need to set the correct flag?
