T1) select the "GlowObject"
T2) assign a material to the object, then assign the AfterGlow Plugin
T3) the "Texture Number": give the object a number for identifing reasons
T4) back in the material window select "win" (thats important for the right coordinates)
S1) load the Scene into the Sequence-Editor (Shift F8, Shift A)
S2) assign the same AfterGlow Plugin to the Scene-Strip
adjust the values (n-key); note: Texture Number -1 means, that all objects with the texture-plugin glows.
Change the number to the one from T3 if you want only selected objects to glow.
The very first rendering returns a X. Thats not a bug! This occurs while checking the rendering-resolution.
"Show weights" is for setup and testing only. Maybe not really useful for you.
"Animated" allows you to animate the GlowEffect ;).
AfterGlow puts some information in the Xterm while rendering.
AfterGlow provides some special features to Blender to have a gloweffect. But it may doesn't work in every case!!! Sometimes you have to check and adjust the parameters a lot (sorry.).
Don't forget to enable "Do Sequence" before rendering (F10-Menue)
