I made the decision to buy both Programs. I don’t feel bad about it at all. And now I have some contacts in here who I can ask the periodic question to after I get into both more. I got an extra $5 off becuase steam is also doing their summer sale promotion. It was a nice cherry on top of the decision!
Thanks everyone for your input. I realized that Substance has some Unity features that I also wanted to use and I believe it works with my Unity Amplify Shader Editor that I also own for Unity, so that helped in the decision making process.
