Hi.
Iv touched some areas of rigging, setting up constraints. correctional morphs. Feedback in viewport is fast and looks so nice. I had to mainly deal with modelling tasks. My daughter was doing a Graphic Game Media course at college. She naturally came to me for help. They wanted proof she did the work in Maya but also allowed some work to be done in C4D. My daughter didnt know Maya an neither did I and the tutors didn't either lol. I started doing some training for Maya, just basics and using my intuition crossing between C4D and Maya. After a sort period about 30 hours I was getting things done and felt regret that I could not own it outright as I liked it, so didn't pursue learning it further because it was too expensive. My speciality is in Digital Sculpting and anatomy study which opened up to being a generalist, but had always wanted to understand rigging.
Going way back my first rigging experience on a basic level was in XSI, then I took a course rigging in Max, this was enough to let me know rigging as a speciality was not for me, it gets way too technical, much deeper when your having to write scripts and rig hard surface objects e.c.t. Not giving up on rigging I then as a beta tester for DAZ3D for all their software range delved into rigging with DAZ3D specialist tools while working with a DAZ3D colleague on a project. I later moved on to Modo where again I touched on rigging characters. I got to rig some cartoon based characters in MODO where some past aspects of Max finally clicked with me. I hit some limitations in MODO and combined it with Messiah Studio, learnt some cool stuff in there, done some rigging training in there too. Next was C4D where it sat bang in the middle between Maya and Modo.
Iv seen some exceptional character rigging done in C4D, and some great modelling, so while Maya, Modo may be better in some areas a lot can be said for being proficient in where your comfortable working in. If your working in software that's better but you feel your fighting against it you will not work fast, this is how MODO left me feeling often.
This may be where Jay is coming from, he knows C4D well enough and feels comfortable enough to be very efficient with it and get the job done.
