Hi experts,

I try since hours to change a text object during animation in blender 2.63. I want to realize an image count in an animation film. It is clear how to change the text in a text object:

Code:

bpy.data.objects["Text"].data.body = "frame "+str(i)

My setup is an Inputnode (Movie Clip) and a Render Layer with the text object. I also know how to render the animation using python:

Code:

bpy.ops.render.render( animation=True, write_still=True )

But I have no idea how to implement a kind of a loop changing the text object for each frame of the animation.
Can anyone give me some tips? This would be very nice and help me a lot.

regards,
_patrice_

how about using a handler?

if you add the text changing code to frame_change_pre, it will be executed right after frame change but before rendering.
