Hey, don’t know if this a fuse or a general vvvv issue.
It works when adding a typed pad / io-box inbetween.
Tested with 5.0 stable and Fuse 1.0.0.0-alpha04.
FuseGeneric.vl (20.5 KB)
I would say this is the expected behavior because there is no otherway to resolve the type the shaderNode type has a so called monadic feature that convertes Vector4 to ShaderNode by using a defined conversion function in case of the vector 4 it creates a gpuIn . Not sure if this monadic feature of vl could be extended for your usecase will check with elias. But otherwise add this to a help patch so that at least people are aware.
Thanks for posting its a good find.
