I’m using a particle system with an animated bitmap on each particle, and it’s rather important that the bitmaps run according to particle-age, rather than all being in sync. And it seems there is a checkbox to make exactly this happen in the Time rollout of the Bitmap window in the materials editor.
However, I find out now that this functionality isn’t supported by the Mental Ray renderer, which is the one I am using.
MAX does this a lot, it seems: some things only work in one renderer, some only work in the other, and you need both effects in the shot you’re rendering.
So, what I’m asking is this: is there an alternative?
It seems that, on occasion, MAX offers the same functionality for different renderers, but under a different name, or it requires a different type of object, or some darn thing…does anybody know how to make this happen?
