Have been experimenting with meta-objects, but came across this:
In Blender 2.33
Add bezier curve
Add meta cube
Parent meta cube to curve
Set curve to “curve path” and “curve follow”
Set length to 5
Select meta cube
Click on dupliframes
Everything works fine until I try to render, and then it pauses and crashes.
I tried the same thing in 2.32, without a problem
Is this a bug or something? Any ideas?
