Mesh Particle SubImage index not playing sprite sheet

I have a mesh particle that I’m trying to play a SubImage index on, and while the sprite sheet shows on the mesh, it doesn’t play.

Under the ParticleEmitter>Required>Sub UV I have it set to the tile grid size (6x6). And under the ParticleEmitter>SubImage Index I have the points set up to (0,0) (1,26). I feel like this should work, but maybe the system doesn’t allow flip books on mesh, could this be the case?

-Cheers and thanks for the help.

That was the trick. Thank you.

make sure your texture sampler inside the material editor is a subuv one, else it wont work.
