Here you can edit the execution options of Xpressionist.

Start Frame

here you specify which is the first frame on which Xpressionist will execute. The default value is 0 since you normaly want Xpressionist to execute on all frames. If you work with indexed variables you need to set a later start time for Xpressionist to avoid errors.

End Frame

Check the box and specify a frame on which you would like Xpressionist to end its calculation. If the checkbox is off Xpressionist will calculate on all frames after the Start Frame you have set above.

Every Nth Frame

Enter a value if you want Xpressionist to only execute on every other frame. Default value is one which means that Xpressionist will execute on every frame within the range you have specified above.

Set Keyframes

Usually Xpressionist writes custom frames to the cells in the project window. When this checkbox is checked Xpressionist sets Keyframes on every frame it executes instead. You can adjust the time spacing of keyframes set by Xpressionist with the Every Nth Frame option and the Start Time and End Time.

Update All Frames

When this checkbox is checked Xpressionist will calculate not only the current frame but also all other related frames in the project. This can be useful when you have written a script with a simulation that starts with an initial condition on which all other calculations are based. When you change a value later in the project all previous frames have to be recalculated to reflect the correct state of the animation. This behavior is also known from some particle plugins.

Note: Only use this option when you need it. Checking this checkbox can result in dramatically increased update times.

Mute

When you check this option Xpressionist will be muted.
