Thanks, I'm more just interested in just browsing through the graph for these filters to learn how they were implemented (more specifically how they seem to blend so nicely with the underlying materials). I realize the techniques in them are likely nothing groundbreaking as far as substance goes, and could probably be learned elsewhere as well. But for someone just starting out learning the substance workflow, i think the more opportunities to see how these types of things are implemented the better.
I had also just started building basically this exact pavement filter in designer (for use with a hand authored tile pattern) so I figured having the source for the pavement graph would be a nice head start there. But alas, it seems I'll just continue trying to puzzle through it from other available graphs out there.
If the technical constraints of sharing these SBS files can be overcome, I think it would be really useful to have access to the source.
