Hexagon and Carrara were free in magazines like 3D World and 3D Artist. I think DAZ Studio is free. I've tried Blender and others for modeling. Too slow and cumbersome. I much prefer modelers like Silo3D and Hexagon that are, right away, intuitive and focus on just modeling objects quickly without user interference (UI).
15 years ago, 3D modeling hobbyists were a thing. Hundreds of new posts a day on forums, and hundreds of images uploaded to galleries. But software jumped in price by +$1,000, or went to subscription fee models where you pay every year or six months to use an app. Hobbyists left the hobby in droves when they couldn't afford the software they were no longer even the customer base for.
All those 3D sites have become cyber ghost towns pretty much. Mostly just adbot click-bait sites now. And career people that use 3DS and Maya don't post in forums because of NDAs. I heard that Lightwave has been dying on the vine. I tried it once. Too slow to model stuff quickly in. modo sort of came from that app. I had high hopes for modo 10 years ago. I put lots of money into it (buying each upgrade) before it too priced itself out of hobbyists hands. I never could figure out how its modeler worked. So I only used it for its rendering, which was better than everyone else's for the price at the time. I even did CAD stuff back in the day. The price of CAD software has gone up too by $1,000 since I last bought one. Vue Infinite has shot up in price, too.
High price for little new features added with each release helped people decide if they should continue updating their 3D software or not. 3D-Coat is one of the last current apps that has not gone overboard with its pricing. And is still easy and quick to use. I use it for painting my models. It does far more stuff. Mostly, it is for creating game assets quickly that can be used in 3DS and Maya pipelines. Something that modo tried to do before it became a full-on movie production app of its own like 3DS and Maya. But I use 3D-Coat for just exporting painted models into my simple scenes for rendering.
The next thing I want to model is a vacc-suit. Maybe even rig it to make it pose-able in Poser, for rendering in Vue. I'll have to look around first for some vacc-suit ideas that a Traveller might use. The trick is not having the Poser figure look like a Poser figure in a rendered scene. I can't stand Poser art.
