NullReferenceException on Calc Lightmap

Unity Engine
1

Hi,

Every time I click the “Calc Lightmap” button an exception appears on the console right when the lightmap wizard pops up. Any idea what causes this?

i did a clean reinstallation of unity3d. the error is still there. tried it with a clean new project and a new scene. no luck. did you solve the problem?

This looks like it might be an error in the lightmap script. Are there any unusual circumstances as far as you are aware? (For example, letting you select the Create Lightmap command when there is no terrain in the scene.) Are you using OSX or Windows?

tx for reply. i work with vista64. a month ago it ran like a bat out of hell. the error only comes when first selecting the terrain, then in the terrain settings menu of the inspector the error occurs by clicking on calc lightmap…

when i do the same over pulldownmenu from “terrain” top, the error does not come. strange? … hmmm. i tested some around like trying to do a lightmapping without a terrain. the menu was greyed like i aspected. only the possibility to create a terrain.

btw, we will use unity for architecture-visualisation and game-demos. the tool is very promising.
