also not sampling textures by any means.

No, it works in some situations... but you have to be very aware of the limitations (which isn't very well documented I heard). Like, problems with clusters, problems with 2ndary or primary rays turned off somewhere in the pass, reflection, refraction and so on. We have been using RSMB for FxTree (very fast) or AFX and XSI MB (sans Rasterizer, for rotating things and so on) a lot lately and it works quite fine.
Stu spends most of his days rendering Lambert spheres... I guess thats why it works out for him. ;-)

It woks for you ? I'm interested as it looks completely broken to me. You use 5.01 or 5.(secret) ?

    Do you have the Rasterizer (a.k.a The Root of all Evil) on?

        isnt there a known bug in 5 with objects randomly disappearing
        with motion blur?

        Nope, geometry definitely not intersecting and renders fine
        now that I've re-jigged the textures to avoid cluster
        materials. Reckon I'll CAB the dodgy scene to Softimage.
        (expensive fare – ho! ho!)

        I'll bear in mind the close faces thing, Kim. Thanks guys : )

        are you rendering both front and back faces? possibly the back
        faces are coming through and obscuring the front.

        close together faces, apart from giving problems with depth
        sorting, can hammer render times I've found in the past.

            Hi folks,

            I'm animating pages of a book (using IK chains) and so
            need to check 'Deformation Motion blur". Only trouble is
            that the cluster material on the B side of the pages goes
            black - huh ?!?!

            I can workaround this by making a texture for A and B
            sides in one image and redoing texture projections, but
            wondered if anyone else has found this? is there a fix? Or
            is it just another case of avoid cluster materials at all
            costs!

            Cheers,

            Olly xxx
