I'd like to upgrade to the Pro version, but given the high cost, I'd like to be more cautious about the investment.
As a long-time user, I can encourage you to upgrade to the Pro version.
Since RC is only using 3DSMax`s capability in geometry modification some tasks could be tricky but Itoo has great support and community and 99.9% of problems were solved as far as I track.
From your questions, I can see you are targeting a solution for the specific job at the moment (maybe I`m wrong, sorry) but I assure you you will be using RC Pro in every future job, so investment in the Pro versions booth for FP and RC is the right move!
We are all here to help, welcome.
P.S. I need to save this message and re-post it again every time new users are in a dilemma whether to upgrade to the pro version.
