Hi Guys,

a test the motion blur 2d and 3d. I have animate a checker texture on the floor, but that donīt want blurr. Why ?

It's not part of the temporally interpolated parameters.

If mental ray would temporally interpolate every single thing in the scene, motion blur calculations would be excruciatingly slow.

So this is completely normal and as-designed.

Sorry Masterzap,

but FinalRender and Vray have no problems with animate texture. I think mental images must resolve that problem.

FinalRender and Vray both use max shaders (built on top of the max shader subsystem - at least originally), which has a temporal evaluation (i.e. the TimeValue "t" is a fundamental parameter of a lookup of any shader).

This is simply not how it works in mental ray. It would be a monumental task to redesign mental ray to have the concept of time in the texture evaluation.

Of course, you CAN do this if you add an interpolation shader yourself based on state->time which "knows" a parameter value for t=0 and t=1 but it's not something happening automatically in any way.
