Hi Folks!
A friend is working on a shot where he has to make gradually smaller copies of a scene with a camera zoom in, he wants all of them to look the same so that it can loop seamlessly. If we make the lights in each scene include only the objects in the max file, when we xref it multiple times we get consistent lighting. The next issue is now reflections where we don't want a model from one xref to reflect anything from another. Since there's a high object count I want to script trace sets so that it'll loop through all geo in the scene and add in every object in the scene except itself. This should be fine but I'm getting a dependency loop error. Any thoughts as to why the assignment doesn't behave?
Here's my code which is less elegant than dave wortley's, who is also getting the same error:
On a simple scene with a box, sphere and a teapot here's my error log:
Any thoughts?

Code:
theObjs = geometry as array
for i = 1 to theObjs.count do
(
format "debug: working on object % \n" theObjs[i].name
theTempArray = (for g in geometry where [URL="http://g.name/"]g.name[/URL] != theObjs[i].name collect g)
print theTempArray
theTraceSet = vrayGetTraceSets theObjs[i]
theTraceSet.reflect_exclude = theTempArray
--theTraceSet.reflect_exclude_type = 1
--theTraceSet.refract_exclude_type = 1
)
Code:

Any thoughts?
I found another trick to avoid dependency loop. Let's say you have multiple teapots and multiple spheres that should exclude each other. So no teapot should reflect a sphere and no sphere should reflect a teapot. You would run into the dependency loop issue.To avoid it one can group the objects. Now instead of excluding all the teapots individually each sphere excludes just the "group of teapots" and all teapots exclude the "group of spheres". No dependency loop.
