Just out of curiosity I was wondering if it was possible to render in reverse.

I have a render and I suppose i could just use after effects to reverse it. but I tried entering frame 190 as the start in render settings and 1 as the end. But it won't render a result.

am I missing some thing or is this not possible in maya?

see the render below.

I just want to see the effect in reverse, as the particles form the text.

Any advice would be greatly appreciated.
