Overflow in addobject....

Hi, I have a trouble to make oct file.

I got an error message like below when oct file is created.

oconv material.rad room.rad blind.rad sky.rad > test.oct
"internal - set overflow in addobject < blinds.41.0 > "

my blind.rad file has 69 blinds polygon in it.

blinds_mat polygon blinds.41.0

                 -1 -0.5 5.9347826087
                 -1 -0.558689862838 5.87609274586
                -14 -0.558689862838 5.87609274586

Any idea what makes this problem?

If I remeber right it has to do with coincident or objects very close to
each other in your scene.
Did you try to use the -r parameter? The man page of oconv explains, what it
does.

Usually, there are three reasons that the oconv process can blow up like this:

   1. duplicate geometry - do you have overlapping geometry for the
      blinds (eg polygons on top of each other)
   2. scaling - some piece of geometry that is being built seperately
      and then xformed into the scene at the wrong scale
   3. density - lots of small geometry clustered tightly together in a
      large scene

In some of these cases you can work around the problem by increasing the octree resolution (-r), you can take a look at the man page for further information on this.
