DR with overide material switched on crashes max 7.5

[sany]

If I have override materials switched on and I try to render/calculate GI only, using DR in max 7.5 I get fatal crash with no warnings.

The funny thing is that it appears as though it does the calc correctly except that all DR node buckets stay visible and when they finish calculating there bucket they go to the next section without revealing the calculated portion, so I get a VFB which is covered in buckets except the ones calculated by the host system.

Hope this makes sense, if not let me know and I'll try to clarify the problem?

could you post up some images to show what the problem is?

For this render I was using 4 render farm units each with dual processors, so at any one time there should only be 20 buckets showing. As you can see from the image there is a lot of repetition. what happens next is that when the prepass is meant to come to an end and the rendering is supposed to start, that's when max crashes.

This happens every time when using DR and Override Mat is on. However if I uncheck override material and apply that same material to the entire scene I don't get repeat buckets, a crash and the image renders start to finish without glitch.

Hope this helps.

Thanks

PS: Note that the areas of the image which have been correctly calculated/have no remaining buckets showing, were processed by my workstation not a remote one.
