I agree here, whatever works best for you just go for it, however one could have the most incredible models/animations/materials but without solid mechanics and functionality the game won’t be all that fun to play. I spent the first 3-4 months on my project solely on c++ code,BP and widget creation, now as I slowly work on visual assets it’s pretty easy to tweak, perfect and replicate mechanics to seamless just drop them into position and have them work as intend with little to no troubleshooting. Best of luck friend
