The error code 144 means that you are out of memory, simply put your
scene / object is too big, I could be wrong as I don`t have the manuals
with me right now, but I am pretty certain thats your problem. Here at DMU
we have similar problems. The main cause is not enoght RAM: we have
around 64M/Bytes on our Extremes, and this crops up quite often.
So what can you do? well there are a number of solutions the first is to buy
more RAM :-) Alternatively you can increase your virtual memory by assigning
a larger swap file, this should help if your swap file is currently quite small in
relation to your total installed RAM: If you are rendering in the background
with Alias still running you might try saving your SDL file manually, quiting
Alias (this will free around 10M/Byte+) and starting your render from the unix
command line .... i.e.
renderit -r raytracer /tmp_mount/usr/people/gary1/user_data/demo/sdl/myscene.sdl
If this still fails you will have to take more drastic action, although you could
raycast your scene instead of using the raytracer. This won`t give you nice
real-world reflections and refractions, but it will save you quite a lot of memory.
If all this fails then you may have to stream-line your model, by deleteing or
simplifying complex geometry. If you have a lot of lights (especially spots)
you might want to remove as many as you can. I have quite a few scenes
that rendered fine until I started adding lights. Even when raycasting spot
lights require huge amounts of RAM: for shadow maps. you might also want
to reduce your surface subdivisions in Object Mod->Render Stats, by altering
the U / V subdivision parameters.
Hope some of this helps ... -Gary-
