Seeing something I haven't experienced before.....

I have a model of a tire. Its made of 3 surfaces and a poly surface (2 side walls, a polysurface tread, and an inner wall that wraps around the wheel). The inside side wall, tread and inner wall all use the same material while the outer side wall has the same material with displacement for the Logo and markings. All materials have been applied by layer (however, i have tried assigning by object as well) and am seeing the following issue....

I am wanting to duplicate this tire 8 times in my model....
I select the tire components described above and "Block" them naming them after the tire model.
Test rendering at this point (simply after block creation) looks great...I see the displacement and the materials act as expected.
I select this block and copy. Copy from one alignment point to another on my c-plane.
Now I have two tires.
Test render at this point and suddenly there's no displacement.

I have tried inserting the block rather than copying it and am seeing the same result (no displacement).

Any ideas?

Displacement is not supported on instances in Maxwell. For future reference, instances also support neither motion blur nor the assignment of emitter materials.

Thanks JD.
That explains it.
I had figured as much in terms of emitter and motion blur but the lack of displacement support is a bit of a surprise.
Any possibility of future implementation?

By Maxwell, I couldn't say. However, with all this work on Fire, I've been rewriting pretty much all of the plugin's export code, and in the process gaining the ability to, for example, check for emitters on an instance, and export another copy of its mesh instead, thereby circumventing the engine's limitation. It should not be difficult to extend that to displacement too. So, will you render instances with displacement? No clue, but maybe you'll render blocks as meshes without manually exploding them first. I'll check into it.
