You can input that as a driver for some property, as a Python expression. Something like, (e ** ( -0.7 * frame)) * 0.1 * cos((14 * frame) - 0.9) but I didn’t check my parentheses very carefully or use your exact constants and I used periods as decimal markers (not sure if regional settings are going to impact that for Blender.)
Although that particular expression is going to spend a lot of time very very close to zero…
If you want it as an editable f-curve, you can use the “bake action” operation to write it to keyframes.
Dude, thank you very much! I’ve been struggling with this about a day now and you just saved me!
You can also create your own driver functions in Blender.
import bpy
def mydriver(val):
return val * val # return val squared
bpy.app.driver_namespace['driverFunc'] = mydriver
Then you can use this as a driver in any field that takes drivers.
