Has anyone heard when this will implimented? next update?
I have read about somewhat of a workaround by using a glossy map but this doesnt get bump does it?

HEy! I'm glad you posted these questions.
I ddint know that the plastice worked without a bump on it, that would explain why MOSDT of my plastics rendered without a BUMP. BUt the Reason im responding is that Ive found a strang inconsistancy in this plastic bump malfunction, as SOme of my Plastics DO render with bumps, weird huh?..

Ok so Here the First Im age I have Plastic assigned to MOST objects, exept the person and the main Median models, But I've had plastics on the Toll booth models, the Concret Columns are Plastic and they render with a Bump , yet the concrete boxes around the pillers have a Plastic bump do not show evidence of bump rendering on them, which is weird cuz when i assigned a Plastic to the graound and gave it a Bump it worked great.
So im gonna try and figure out what it is about the geometry that maybe turns the bump on and off on the objects.

so heres the First image with the Bump clearly showing up on the Columns.
Thew plastic has a Spec color of whit at a value of .25 and a bump of 500.

the 2nd render the plastic has a SPEC of .6 and a bump off 500 just to compare that the spec on the plastic renders too.

Hope to come up with a solution to the Phantom bump soon.

Here Is another render I've Updated from MAxwell Alph to BETA, and Its a Bump on Plastic, and it rendered fine.
So im convinced maybe there is something we can to top Geometry in maya to allow plastic to render with it, since only some of my plastics dont render bump.

i love the plane rendering, very nice!!!
I have found that some will render if the texture if perfectly square. But that only works sometimes as well, so i cant figure out why some will render with bump, and some wont :(
