Welcome, mate!
I bought a few disks from First Computer center and I also messed around with raytracing on the Amiga from 1996 to 2001 (Real 3D 1.4 then Cinema 4D).
Mine is an A4000T, and like you, I had to defect to the Dark Side and use a PC for my research. But I can't bring myself to dump the ol' girl (the Miggy). There's a history between us.
It's about nostalgia. Plenty of knowledgeable people on this board, so welcome to the right place for classic amiga users...
