Strange bug...can someone help me figure this out?!

[RSF]

Hello
I posted some days ago about a strange problem with "distributed render"
I tried to isolate the problem and I got to this sample scene.
The scene is just a box with inverted normals and two mat id's.
Inside the box are some standard spotlights.
There is one object outside this box wich seams to be causing the problem (object01) but the strange thing is that if I copy this object and remove the original everithing's fine again
Here are the two renders without and with this object and the max scene

This problem disapears if I turn off interpolation for the materials reflectivity or disable "use light cache for glossy rays" in the light cache settings but nevertheless this seams to be some kind of bug.

In the attached scene there are two objects outside the box.
Object01 is the one causing the problems, object02 is just a copy of the previous and works fine.

Can someone help me solve this case??

Thanks

Hi.
Did someone at least reproduced the problem??

I could not reproduce this right away; which 3dsmax version was this?

Best regards,

Hi Vlado.
I'm using max8.
This is probably a corrupted object issue that messes things up but...nevertheless I think it would be usefull if the exact cause could be found.

Is Detail Enhancement on?
I had similar problems with DE on a flat glossy plane. The geoemtry color was bleeding through on some buckets on some computers.

Hello.
Anyone reproduced this bug?
I'm not using edge enhacement.
This is really really annoying because I never know when this scene is going to turn like this and have to go back to an older file just to avoid this.
I was able to isolate the problem in the attached file and would be nice if someone could at least reproduce this behaviour
Vlado? Anyone!?
Thanks
