	Oh, i'm just learning myself python by doing this little modification. i'm giving myself a few aims (inverting faces, applying materials, automatically positioning and scaling) and try to realize them. ''If'' it becomes useable without having any disadvantages i'll incorporate it into the main script, but we'll see.... the main purpose is to get a hold of the python language (and the Blender API). --[[User:pontiac\|Pontiac]] 09:49, 27 Sep 2005 (PDT)		Oh, i'm just learning myself python by doing this little modification. i'm giving myself a few aims (inverting faces, applying materials, automatically positioning and scaling) and try to realize them.

	You're overdoing it. KISS. The purpose of the howto is to show the general technique for baking radiosity - ambient baking is a good application and serves as the example. And the script itself made ''only for transfering vertex color information''. Baking glowmaps is an application just as good as ambient baking, and even if you're baking ambient light you don't always want to utilize a sphere as the lightsource. And if you do want a sphere adding one is simple, and usually done once per project, so the manual labour time is minimal. --[[User:tiny paintings\|tiny paintings]] 09:38, 27 Sep 2005 (PDT)		You're overdoing it.
