Hi folks.

So I'm trying to get mental ray to render a bunch of STATIC particles that are no longer dynamic. I have assigned a lambert shader to them, with a sequence of seven images, generated randomly at creation via a SpriteNumPP expression. They are shown correctly in the viewport (see first image). These colors are assigned from an image sequence - NOT from rgbPP, and that's how this has to remain.

Now, when I do a Hardware render, the colors are correct, but when I do a Mental Ray render, the colors are all the same (see second image). The color that they will have seems be the current image sequence color, which is not what I want...I want the sprites to keep their various colorations that they show in the viewport. My guess is that MR is reassigning the current frame's image file (see third image) to ALL of the sprites, but I don't know why...

Anyone have an idea about this?
