Arnold Noise Seed Static

As the title says, in all of our renders the noise is static, even if I try animate the seed it doesn't change. Is this intentional? We are using noice too, surely cross-frame denoising also works better with different noise patterns per frame?

I bet if you export an ASS file, AA_seed is not set.

Try putting this in Arnold ROP > Properties > User Options

AA_seed $F

Oh my word that worked thanks yet again Stephen!

Just to be sure, is it possible that I did something wrong on my end, or possibly a bug in the build of htoa I'm currently using? Doesn't seem like the htoa rop parameters really do anything to the seed.

I think this happens when the Arnold ROP was created with an earlier version of HtoA. Not too long ago, we changed how the AA_seed was exposed in the Arnold ROP, and I think the resulting mismatch messes up things.
