That's plausible. In fact not only renderers have safe guards but also the DCC itself has it. I remember scaling objects to zero in SI|3D and the geo goes poof :) What does make sense in a way. When XSI came out, I tried that and I could rescale it back to normal size what means that under the hood XSI prevents that also. Some animators I came across scaled objects to zero in XSI to make them disappear in an animation. Similar to replacement animation. It never felt good to me..like throwing something inside a black hole/singularity :)

Doing so often induces crashes in the renderer because it produces triangles with zero area (many algorithms depend on non-zero area), or sends zeroes into parts of equations where zero is illegal (divide by zero, for example). mental ray has implemented safeguards to catch most cases, but it doesn't catch all cases. I'm somewhat sure the same is true for other renderers.

Well, that would possibly create problems with camera fly-throughs and reflections :) BTW I wonder what it means for the renderer I you would scale them to zero. I never did that with masters in a scene. ------ Softimage Mailing List.
