Had the same Issue a few weeks ago.
After multiple failed Renders, i recreated my Groups.
Added every Object one by one, to be sure they have the same Ordering....
So:
Add Object_A_01 to Group A
Add Object_B_01 to Group B
Add Object_A_02 to Group A
Add Object_B_02 to Group B
Add Object_A_03 to Group A
Add Object_B_04 to Group B
Add Object_A_05 to Group A
Add Object_B_05 to Group B
[...]
But... if you only want to change the Material....
Put the PointCloud and all Shapes in a Partition and assign the BlackMat
to this Partition
Or, if you only want to get a Depth-Channel...
Add the "Depth" to your Pass-OutPuts
Also.... Try "Enable Filter Numeric AOVs" in your ArnoldRenderOptions
(sometimes Helps, sometimes not)

we have a problem;
pointcloud A scatters random geometry from group A on a surface
pointcloud B (which is a duplicate of pointcloud A) scatters random
geometry from group B on the same surface
with me so far?
the purpose of this is to have the same objects (Arnold standins of
trees) on 2 clouds, Colour ones for RGB, black ones for depth pass
(you can't override standin materials, scattered with ICE.... go figure)
problem the two clouds pick DIFFERENT random objects in each case,
they DON'T MATCH!
i have a scene to repro if anyone fancies a look..... this is a Soft
problem (the override thing is arnold's)
the workaround is to duplicate cloud A, freeze it, and in a new ICE
tree, reset the shape using a copy of the original portion of the
original ICE tree
confused? we were...
