Yeah, render the mix out to where its done, start a new project, for mastering. So you just have a fresh project with a stereomix.
Then in my workflow, i use a high samplerate (which also means i have to upsample each mix sent to me, a bit overkill when youre starting out) so i deal with aliasing differently; which means if i use a plugin without oversampling i have to use a LP filter after those steps. And also, I render each step that uses Lin phase, so usually my masters are 3-4 renders before the final export. I try to chain together plugins that feel like they belong together. So for example, first render is the corrective lin phase EQ. Then 2nd render is the rbass; compressor and another EQ. If im feeling extra that day, I render rBass in a seperate render. With my cpu and samplerate a render can take some time; anywhere from 20 sec to 3 min dep on oversampling and type of plugin (limiter + clipper step is the longest for sure) so its a bit more time consuming (and ALOT more data consuming!!) but if Transparency is your true goal with it has become for me I feel that is important.
3rd render (which is often the final export and not a 'render down/render in place') is usually clipper + 2 limiters. sometimes i add extra processing like a MB or something; for a 4th render; But thats a bit overkill for a new producer starting out to master - i think youre better off using the same samplerate as you export your mix in, then just put everything onto one chain. and dont worry too much about letting some plugins render down; and chaining some together. at least start out like that to get a feel for it. Hope that made sense feel free to ask
