Octane can't render image sequence as alpha map

[18500214024fsy]

I have faced this problem for some days.I use a image sequence as alpha map And apply this material to some selected polygons of a object.This object already has a material as global.
The problem is that the image sequence never plays.But when I switch to the defalut material ,it all works well.

Of course it can render, but here it cannot detect the updates. Put Octane Object tag and use "force updates" parameter.
