You are good to go.

Get started, see what you want to do, find where your bottlenecks are and deal with them when the time comes.

I'm about 18 months in, I want to do photorealistic animations.

I started, my scenes got big - first bottleneck: RAM. Upgraded from 4 to 12. Sorted.

As I learnt the material room, my renders got more realistic, and render time grew exponentially. So now I am exploring other render machines (see my other thread).

Dive in, get started, have fun. It's a bit like learning guitar, when you start, you don't know how good (or not so good) you might get, there's lots to learn, and the more you learn, the more other stuff you'll find that you want to learn.

Poser is a great introduction to 3D, you can do brilliant stuff with it, there are some things it excels at, and you certainly can have a lot of fun with it.

Questions? Try a search here or RDNA, otherwise just ask. Very friendly folk about.

Just don't look at any Poser galleries, here or anywhere else, they are all full of splunge! (There is some excellent work about, but, by Zarkon, you have to search for it!)
