I've been using the UVW Randomizer extensively in my last several projects and I want to echo some earlier comments that it is cumbersome from an interface perspective - I feel like I have to wrestle with it to arrive at the desired behavior and I wonder if a 'jitter' parameter might be useful(?)
Additionally, I find that I am using the UVW Randomizer a lot, which translates to setting up the UVW Randomizer a lot, and that can be a tedious, if not lengthy, process. Similar to the Corona Triplanar node, I am curious if there is a modifier-based solution or a way to fold the UVW Randomizer (and triplanar) nodes into a global shader dialog, e.g. advanced options?
