Hi,

I am trying to use the Ocean Tool of Houdini and testing how to accumulate cusp attribute over time.
I though I would be be simple with the Sop solver but I can' t achieve the accumulation.
The ultimate goal is to add the cusp value of the current frame to the fading value of the old ones.

In the example scene attached, you can see there is no accumulation and no fade. Only one cusp layer ( with anim) over another ( animated)

Thanks for your help.

well I really can't figure what's wrong.

I made a similar thing with attribute transfert and it works as excepted …
