Default Null Ptr Exception - 02-22-2013, 07:39 AM

I have sent this file to support to see what can be done with it...

It has an exceptionally large number of models in it, which can cause problems for Alice as the size of the world approaches the allocated stack space in the system for the program.

May I ask, did you use the clone tool in the scene editor to create all the models, or did you add each object individually? The clone tool was designed for scene decoration and can sometimes save space when using lots of objects. (It does have limitations, and can cause problems when you try and animate any of the cloned objects.)

Finally, with my students I recommend that they build the basic structure of their world, with a minimal amount of scenery to start, get their animation working, and then start layering in the additional scenery, saving frequently, and with different version numbers, so that if and when they encounter the problem you seem to be experiencing, they can go back to an earlier version.

I will let you know if an when I hear anything.
