After several failed attempts with Sampler, in order to create transparent fabric (be it nylon fabric or chiffon), I'm not too sure how to start in Designer. Tutorials allow to understand the global process but for a specific purpose, without experience it's kinda diffucult. Any hint would be a great help.
If you elaborate more it will be easier to nail the issue but the general idea is simple, if you want the holes in your fabric to be transparent you just have to have a grayscale image with black/white (white is opaque and black transparent 0% opaque) and create a output and set it to Opacity and don't forgot to "view output in 3d view" and choose opacity.
Thanks a lot, that' exactly what I need to start.
Glad to help , good luck.
