Utkarsh, Thanks very much for that! Yes, after some fiddling, I got it to work, i.e., I can save .png files for an animation! So now that I’m using the Programmable Source(RequestInfo) script to accomplish the animation, how do I, during a PV session, *easily* switch back to render a single file?
For example, I can do: frames = range(0,801,100) # render every 100th frame, including 800 setOutputTimesteps (self, frames) or, I can explicitly list specific frames: frames = [100,101] so, I thought this would do a single file, but it doesn’t (my previous frames are still there): frames = [600,] -Randy > On Dec 6, 2017, at 10:44 PM, Utkarsh Ayachit <utkarsh.ayac...@kitware.com> > wrote: > > Randy, > > You attempting to mix the Python scripting for data processing and > Python scripting for batch scripting.
