Ahh ok i thought that set_glow_intensity() changed something with the animation.

If I want to fade in to constant glow, how would i do that? My guess would be after period/2 seconds replace the animation by constant glow. But then how would the glow be able to fade out?

Anyway this was already a huge help.
Thanksalot ;)

In the documentation it says there are different glow styles like constant. But i can't find how to use them.
Maybe i'm just looking in the wrong places but in Blender under Object info tab where all the other glow settings are i can't find it.
Preferrably i'd like to set the style by code so this would be the optimal solution :D

Thanks in advance
