Hi I have a custom transformer F(a,b) I wish to 'chain' or loop an unknown number of times. (Its a customized raster overlay basically putting b on top of a)   Example  For six inputs features (images): 1,2,3,4,5,6 the followin should be done: result = 1 result = F(result,2) result = F(result,3) result = F(result,4) result = F(result,5) result = F(result,6)   bangs head in wall 😛 How can this be achived?    best regards!
Hi,

 

 

have you read this article on looping with a custom transformer?

A short movie here to show you how to put a Looping Transformer together:

Hi guys, thanks.

 

Seems I have to find another way though, looping is only supported for transformers working on a single incoming feature

 

That means a transformer F(a,b) cant be looped.
