but believe me you pay to use TV3D, and You will never regret.
Don't be absolute about anything. TV65 is in open beta which pretty much means "try before you buy". Having a ton of features doesn't make it suitable for all/any job. And for the millionth time, TV is not a game engine but a 3D rendering engine.
One reason is a community that will certainly help you on any skill level.
Some people have experienced the 'wrath' of the community by posting things like these ...
1. Asking something like "I'm a newbie in programming so i want to ask how do i go about making my own MMORPG?".
2. Posting an easy to figure out question, without doing the least of bit thinking and experimenting or even searching the forums first.
3. Not appreciate the time the community has spend to point you in the right direction but expecting instead a complete code to fix your problem.
Avoid doing those and anything similar and you'll enjoy the help and respect of the community.
