PatchForge just added spot channels and texture builds — are they included?

Yes. Everything in every app is included in the pass and in the Master Key, new features included — there are no add-ons and nothing is sold separately once you are a member. PatchForge can now build separated CMYK TIFFs with named white and varnish spot plates, and the three-file colour/build/cut set for raised texture printing on a Mimaki. Both live in the Export menu in the Patch Builder and under Quick export in the Gang Sheet Builder.
