Aight so the title says everything, when I move the "min wavelenght" channel of the ocean spectrum, nothing happens.. I hant bigger waves with no details so I can add it with another spectrum later..

There is no error message at all so I'm pretty confused..

I hant bigger waves with no details so I can add it with another spectrum later..

use Filter Above Resolution checkbox and slider for that

and then you can use Filter Below for high frequency spectrum and combine those

, nothing happens

to answer the actual question, seems like that slider works only in Phillips spectrum type not with the new default TMA, maybe submit a bug, since it's either an oversight and it should work or at least should be disabled in that mode if it is not meant to do anything

but the filters should get you close to what you want in either mode
