What are you looking to do specifically?
Photoshop has some 3D capability.
Mixamo is a rigging tool used by animators and game designers.
Although not included in the Creative Cloud subscription, the Substance line is there for dedicated 3D builders in the same sense that Captivate is available for e-Learning content creators and Adobe Stock is there for people who need stock images and video assets. In other words, different tools are available by special purchase for a subset of users who actually need them. I have no problem with that business model.
