Help I can't create custom filter from subtance designer to substance painter
Hello everyone,
I'm trying to create a very simple filter in designer, to have it work in painter.
However each time i'm trying to use it as a filter I get the following message:
[Effect Procedural View] Effect selected can't be used as an effect because:
generic output is defined and input doesn't match

I'm trying to achieve this on a black and white mask :

What I need as input are:
- what's already in the mask's layer stack below the filter, so I need to somehow get that information from painter
- And a Noise input texture fore the blended pattern., so it's bascally a slot where I can put a greyscale grunge map
my graph is the following:

inputs and outputs are set as following:



No matter what I set into Usage, it's never EVER working. The documentation is really badly written, it's been the whole afternoon I've been trying to make it work without success.
It's really driving me nuts.
Can someone help me by any chance ?
