What is a nil pointer error?? I am trying to start a large render and it keeps giving me this error everytime it advances to frame 3. Frame one renders fine, frame two renders fine but crashes b4 it can save the frame and advance to frame 3. My only guess is that b/c parts of the file are all over my network its freaking out? When does the new patch come out? Anyone help please?

Alright, anagram time! Nil Pointer:Carrara :: Server Error 500:CGI :: General Protection Fault: Windows :: Error Type 1,2,11, & 12:Macintosh. A nil pointer error is apparently just a catch-all error that covers situations the program cannot describe (a base case for errors). A "pointer" in programming is a data type that points directly to a memory location. When a program deletes/nullifies a pointer, it empties that memory location. If the program tries to delete/nullify the same memory location again, without setting the pointer to 0 (nil) to indicate that it is a null location, it tends to crash. So its basically just a fancy memory error. There is no particular cure for a nil pointer, but I've found that some texture maps tend to choke Carrara. Save the file with the textures saved externally, and then temporarily throw the files in the trash/recycle bin. This may help it run. Nebula Supernova Studios

Thanks. I have a few things I can try yet. I just found out how to change my memory swap on NT 4.0 to another drive so hopefully that will help clear it up. Its not due until the end of the month so maybe I can also try to wait for the patch.
