I use Maya LT ($300 per year). I have an old PS license I bought for a one-time fee a looooong time ago. I bought Substance & Substance Painter ($250? one time fee). Mudbox ($10 per month - not sure if I’m going to continue). World Machine Standard ($99).
That’s about it from a tool perspective. Honestly, before it’s all over, I figure I’ll have sunk more money into Marketplace content than on tools.
